Deputy prime minister says while jets currently only shooting down missiles, there is legal basis for them to do more

• Middle East crisis – live updates

Hello and welcome to the UK politics blog.

Royal Air Force jets could legally strike Iranian missile sites being used to attack British interests in the Middle East, David Lammy has said this morning.

It is entirely legal to protect our people and protect our staff, and therefore all operational capability is available to us in those circumstances.

It is my understanding that that would be legal.

The UK is sending four additional Typhoon jets to Qatar, as well as Wildcat helicopters with anti-drone capabilities being sent to Cyprus, Keir Starmer said in a press conference yesterday. He said the US has been allowed to use British airfields to carry out defensive missions and that HMS Dragon is heading for the Mediterranean.

Kemi Badenoch has said the UK should take offensive action against Iran after UK bases were attacked. “We need to do what we can to stop the ability for these attacks to take place,” the Tory leader told BBC Radio 4’s Today programme.

Shabana Mahmood put herself on a collision course with Labour MPs after announcing a set of changes to the immigration system that one backbencher said mimicked Donald Trump and another claimed would lead to a Windrush-style scandal. The home secretary announced her plans on Thursday, including an end to permanent refugee status and the removal of government support from asylum seekers who are deemed not to need it or who break the law.

A small number of asylum seekers whose claims are rejected will be offered an “increased incentive payment” of £10,000 per person and up to £40,000 per family to leave Britain under a pilot scheme, Mahmood said. The home secretary said the government would seek to echo reforms introduced in Denmark, where she said there had been “great success” in using incentives.

The husband of a Labour MP and two other men have been released on bail after being arrested on suspicion of spying for China. David Taylor, who is married to the Scottish Labour MP Joani Reid, is accused of assisting a foreign intelligence service.

Nigel Farage has described May’s Senedd elections as a “referendum” on Keir Starmer, as Reform UK gears up to battle Plaid Cymru for the chance to end a century of Labour dominance in Wales. Launching Reform’s election manifesto in Newport on Thursday alongside the party’s newly appointed Welsh leader, Dan Thomas, Farage said: “It’s a Welsh election, but I’m afraid, whether you like it or not, it doubles up as a referendum on Keir Starmer’s premiership.”
