Boris Johnson, the former foreign secretary, says MPs will have noticed the “somewhat weaselly” language used by Jeremy Corbyn in relation to Russia.
May says if the two individuals leave Russia, the UK will do everything possible to ensure they are brought to justice.
May is replying to Corbyn.
She says the UK has issued an interpol red notice and a European arrest warrant for the two suspects. But Russia does not allow extradition, she says.
She says the UK has repeatedly asked Russia to account for what happened. Yet Russia repeatedly responded “with obfuscation and lies”.
She says this decision would have been taken at a high level in the Russian state.
They must rein in the activities of the GRU, she says.
She says she hopes that those who were cautious about blaming Russia in March (she is referring to Corbyn) will now accept it was to blame.
She says Corbyn asked for the OPCW to be able to attribute blame. But Russia vetoes this, she says.
Jeremy Corbyn starts by thanking May for advance sight of the statement, and for security briefings.
The use of a nerve agent in Salisbury is an outrage, he says. He says he visited the city.
He says he commends the police for their superhuman efforts in the investigation.
Given the two Russians have been charged, what is May doing to get Russia to cooperate in bringing them to trial.
He says the OPCW findings in this case are a sharp reminder of how the international community must act against chemical weapons.
He says the use of this nerve agent is a breach of international law.
Russia must explain how it came to be used in the UK, he says. He urges May to use OPCW procedures to press for this.
He asks what May has done to hold this to account.
He asks if the government will take any more effective actions against Russia as a state, or against the GRU.
Corbyn says there is no international mechanism for attributing chemical weapons attacks to particular perpetrators. What is May doing to change this?
What lessons have been learned from this?
Corbyn says he condemns the appalling attacks. He says he commends the police and security services for their work.
He says he will support any reasonable efforts to bring those responsible to account. And he condemns Russia for not cooperating with the investigation.
May says in March Russia tried to sow doubt about the UK’s claims. Some were minded to believe them. But the government has been proved right, she says.
May says today’s announcement shows the specific nature of the threat from the Russian GRU.
She says the actions of the GRU are “a threat to all our allies and all our citizens”.
She says we must step up our collective efforts against it.
She says the UK is sharing intelligence with allies about it.
She says the UK will “deploy the full range of tools from across our national security apparatus” to counter the GRU.
The UK has no disagreement with the Russian people, she says.
But there can be no place for the kind of “barbaric activity” seen in Salisbury.
May ends by paying tribute to the people of Salisbury, and how they responded, as well as to the police and those in the intelligence community.
May says the UK’s allies were right to retaliate against Russia after the Salisbury attack.
May says, if the two Russian suspects ever leave Russia, the UK will try to have them arrested.
May says two Russians suspects accused of novichok poisoning worked for Russian military intelligence
May says the government was right to say in March the Russian state was responsible.
Now she can go further, she says.
She can tell MPs that, based on a body of intelligence, the two Russians are officers from the Russian military intelligence service, also known as the GRU.
She says the operation would “almost certainly” have been approved not just within the GRU, but by senior figures in the Russian state. It was not a “rogue operation”, she says.
May says the two Russians facing charges over the poisoning of the Skripals are now also the prime suspects for the poisoning of Dawn Sturgess and Charlie Rowley.
She says if the two suspects were in a UK jurisdiction, there would be a clear case for charging them with murder.
Theresa May’s statement on the Salisbury poisonings
Theresa May is now making her statement about Salisbury.
This was a sickening attack, that left four people fighting for their lives and one person dead. She says in March she told MPs why the government thought the Russian state was culpable.
She says 250 detectives have looked at more than 11,000 hours of CCTV, and taken statements. They have undertaken painstaking work to find out who was responsible.
This has now produced enough evidence for the CPS to bring charges.
She says the police have set out how the two Russians arrived in the country and travelled to Salisbury. (See 11.53pm.)
May is now summarising what was in the Met statement released earlier.
Labour’s Geoffrey Robinson asks May if the government will continue to support his private member’s bill bringing in presumed consent for organ donation.
May says the government backs the bill and will continue to back it.
Labour’s Chris Ruane says Tory Brexiters said Wales would not lose out on funding if the UK left the EU. Since 2000 Wales has had £5.3bn in structural funding. Will this continue?
May says the government is working to ensure that future funds are in place to replace EU structural funds that work for the whole of the UK.
