Prepare for the Beast from the East.

We're drawing our air all the way from Russia,

where it was minus 41 this morning.

The Beast from the East hits the West.

In Salisbury, members of the public were out clearing

the roads to our hospital to ensure ambulances can get there safely.

There have been countless acts of kindness throughout today.

Weather conditions like this really bring out the best in people.

After the big freeze...the thaw.

The West Country became one big family

over the last 26 hours or so...

The community spirit, we know, in Salisbury, is fantastic.

Towns and cities are now clearing, and things get back to normal.

Ah! Paul.

Hi. Dave. Morning. Have a seat.

Tracy, everything you're about to hear is Cat One-protected, OK?

Understood.

The two people who took ill at The Maltings yesterday

are Sergei and Yulia Skripal.

Father and daughter. They're Russian. OK.

Sergei was a high-level MI6 agent

inside Russia's GRU Intelligence Service.

He was moved to the UK as part of a spy swap.

For some reason, they put him in Salisbury. Right.

The initial toxicology results suggest that this is not a drugs overdose.

So, what do we think it is? We don't know yet.

Samples of their blood have been sent for testing at Porton Down.

Mr Skripal's background rang some alarm bells.

Not just with us, in Whitehall,

because of the Litvinenko case in '06.

Do you think this is an assassination attempt?

We wouldn't want to speculate publicly.

Privately, everything's on the table, yeah.

But that was polonium, right? Right.

But the Skripals have been checked for radiation. There is none.

We are setting up a Gold Command operation centre

here in the building

to run the public health response.

Since you're the Director of Public Health for Wiltshire,

we're going to need you right at the heart of this, along with us.

So...any questions?

Anyone else reporting ill?

Not so far. DOOR BUZZER

We have to track back. We have to...?

To track the Skripals' movement up until the moment they collapsed.

Then anyone else connected with the places they visited.

You have to hand your phone in. Right.

For those of you who don't know me, I am DCC Paul Mills.

We're moving quickly here, so if you don't mind, I'll, er...

I'll let you introduce yourselves as we go along.

I've just been informed that this is now a criminal investigation,

to be run by Counter Terrorism Command.

They believe that this is indeed some sort of attack

on two Russian citizens.

So, our job, in this room,

is not to find out who did it,

but to keep the people of Salisbury safe.

This will be multi-agency. National, as well as local.

So we're going to have to work together as a team.

Tracy, would you like to go first? Oh.

Er...Tracy Daszkiewicz - Director of Public Health for Wiltshire.

Don't worry, there won't be a spelling test. Huh!

OK, so the victims show no signs of radioactivity,

but we're still no closer to knowing what the toxin may be.

I think we should assume for now it's something they ate or drank.

Our goal here is to find the source of the contamination.

Ground zero.

If we can do that, then we stand a fighting chance

of locking this down quickly and stopping any contagion.

But the longer it takes, the worst it's going to get.

Um...there's a couple of things I need.

Witness reports from the first responders,

that would be really useful. Absolutely. No problem.

And I'd like to have a look at The Maltings, too.

Yeah, sure. Dave will take you. I still haven't seen the CCTV.

Well, I'll raise it, but it's going to be tricky. Why?

Security services have become involved.

Which ones? All of them.

Look, Tracy, I'm about to go into a teleconference with COBRA.

Probably just a virus. Yeah. Yeah.

That's what I thought. Yeah.

How was the bench cleaned?

I think the, er...Fire Service power-hosed it.

That drain feeds into the water course.

So contaminated bodily fluids would've washed right into it.

WHISPERS: Fuck off.

Where were they before that?

They visited the cemetery in the morning,

where Sergei's wife and son are buried. Yeah.

Drove into the city, parked in Sainsbury's,

went for a pint in the Mill pub, had lunch in Zizzi,

and then they walked through The Maltings, until they sat, er...

..until they sat here.

So they walked all around town. They could've spread it everywhere!

Barricades. Police tape isn't enough.

We need to seal off the whole area from the public.

It would cause a lot of disruption, that's for sure.

And we still don't know what this thing is.

However, that's good reason not to take any chances.

I know it's a tough call,

but there's literally people everywhere down there.

It's half the town centre.

MILLS SIGHS

Thanks.

RADIO: The hospital has said there's a multi-agency approach.

And Dorset and Wiltshire Fire Service say

they were called to the hospital this morning

to decontaminate the area outside the A&E department.

OFFICER WHISPERS

Story's breaking - the Russian angle.

NEWS ANCHOR: Last night, what happened here,

in the centre of Salisbury,

resulted in teams wearing full protective suits

decontaminating the streets, where several areas remain cordoned off.

Police, Fire Services

and public health authorities have declared a major incident.

The first sign something was wrong came yesterday afternoon

when a man and woman appeared severely unwell

in The Maltings area of central Salisbury.

The man and woman are being treated at Salisbury District Hospital.

The BBC has been told that he is Sergei Skirpal. Russian.

66 years old.

In 2006...

Ross? ..he was convicted of high treason in Russia.

Ross? The allegation was that he was a British spy.

In 2010, he was pardoned by the Russian authorities

and came to this country... Bloody hell!

..in return for the release of ten spies from the US.

Police arrived at Mr Skirpal's house in Salisbury...

Got his name wrong.

Wiltshire Police said they were investigating

whether a crime had been committed.

HUBBUB

Yeah?

Hey. Hi. You all right? Oh, yeah, yeah, I'm fine.

Um...we need to find everyone

who was near to the Skripals on the CCTV footage.

The boy with the bread, onlookers.

Find out if they're OK. Public appeal?

We haven't got time for that. We need to make it more targeted.

Their mobiles, that's how we do it. Yeah, OK.

No, not OK. It's not straightforward, Tracy, not at all.

Right. Thanks.

Ah, Professor Atkins? Yeah.

DCC... Very nice to meet you.

Novichok? It's a Russian word. It means newcomer.

It was developed by the USSR during the Cold War,

and it's one of the deadliest synthetic substances on Earth.

It's so toxic that a spoonful,

with the right delivery mechanism,

could kill thousands.

Salisbury Hospital has declared a major incident, just in case.

But if it's so toxic, how come the Skripals are still alive?

The paramedics assumed that they'd overdosed on fentanyl,

so them gave them a shot of naloxone,

which also happens to help combat nerve agent toxicity.

Plus, it was cold,

further inhibiting the speed with which the substance took effect.

So, in this case, they just about clung to life.

For now. What does novichok do to you?

It stops the brain from communicating

with the rest of the body.

A victim loses control of every organ.

They all go into overdrive simultaneously. Very few survive.

But for those that do, what are the long-term effects?

We don't know.

In terms of here, in the West,

the only two people that we know of

that haven't died almost instantly from nerve agent toxicity

are Sergei and Yulia Skripal.

LOW CHATTER

He's in here? Just there.

Detective Sergeant Bailey. And, er...Mrs Bailey?

My name's Dr Haslam. I just want to shine a light in your eyes.

OK. Thank you. I'll be right back.

OK.

So, now we know what it is, can we start testing for it?

The process is difficult.

Let's say we have a deposit of nerve agent here, on this table.

So we want to swab for it.

So we might take one here and get lucky, as it were, and find it.

But if we swab here, just a few inches away...

..it'll come up clean. But it's still there.

And over time, I mean, does it, um...? Degrade? No.

If left untouched, it will remain lethal for a very long time.

How long?

About 50 years.

SHOCKED CHATTER

So, if it's on a piece of clothing, or...?

It's a nerve agent.

Mrs Bailey, listen to me.

I know what this substance is now,

I know what it's doing to his body, and I have a plan to help him.

OK.

OK, so you say Mr Skripal changed his phone?

That's right, yeah. He had a new phone on Saturday.

Is that so unusual?

It's unusual to go from a top-of-the-range smartphone

to an old brick, though, isn't it?

And the thing is...

..I think we were followed from the airport.

You think? Are you sure?

It was a black BMW, two people, a man and a woman.

Yeah, we were followed, all right.

Good afternoon, everyone. AUDIENCE: Good afternoon.

I'm afraid no-one is much going to like what I have to say here today.

The testing process has begun,

but it's going to take at least two days

before we have any reliable results.

We don't know the source of contamination,

or have an established chain of events

about how Detective Sergeant Nick Bailey became contaminated.

Multiple sites are in play.

Zizzi's restaurant, the Mill pub,

various vehicles, Salisbury cemetery,

and, of course, the Skripal house itself.

There will be others that we haven't yet managed to identify.

All we do know

is that this is one of the most toxic substances on Earth,

that has been specifically designed to be invisible and undetectable...

..and that, for the 46,500 people in Salisbury,

we are their only line of defence.

Thank you.

FOOTSTEPS APPROACH

Oh, shit, sorry. I heard the car.

How was the nightclub?

Oh, very funny.

I was watching the news.

You must have had an interesting day.

Careful, it's hot.

How are you bearing up?

I don't think I can do this, Ted.

Oh, not the old impostor syndrome.

Oh, God, I hate being married to a psychologist.

I'm serious.

Oh, come on.

No, I mean it.

This is just too big.

I genuinely don't think I've got the experience.

This is really massive.

What's going on?

What's really going on?

I hardly even know myself.

And what I do know, I can't tell you. Right.

But there are lives at stake.

Maybe a lot of lives.

If I make one wrong decision, just one...

Listen, whatever this is...

..I'm glad you're in charge.

Well, I'm not.

HEART RATE MONITOR BEEPS STEADILY

PHONE BUZZES

I love you.

Is Daddy OK?

Yes, my love.

He says hello.
