UK politics - as it happened: Theresa May ponders UK's retaliation to Moscow after British diplomat expulsions

Theresa May has reconvened the National Security Council to consider the UK Government’s retaliation to Moscow regarding the Salisbury nerve agent attacks.

It comes after the Prime Minister last week expelled 23 Russian diplomats from the UK in response to the attempted murder of a former Russian spy and his daughter. Over the weekend, Moscow responded to this with tit-for-tat expulsions of British diplomats.

On Tuesday, a spokesperson for Ms May said: "The PM said there are other measure that the Government and security officials are actively considering and stand ready to deploy at any time.

Asked at a Downing Street briefing whether a decision had been taken to put in place any further reprisals immediately, they added: "We are in the process of enacting measures which the Prime Minister announced last week.

"We continue to consider other steps. As and when those are brought forward, the Prime Minster has given a commitment to update the House."
