UK and allies issue statement condemning Russia for ex-spy attack
The UK has issued a joint statement with France, Germany and the US condemning the Salisbury attack on an ex-Russian spy, calling it "an assault on UK sovereignty" and threatening "the security of us all".

The Prime Minister stated that the UK government will:
