Keir Starmer was 'kept in the dark' about Israel's audacious attack on Iran, amid growing tensions between London and Tel Aviv.

In a major diplomatic snub, insiders said Benjamin Netanyahu gave the Prime Minister no notice of his plan to mount bombing raids against Iran's nuclear facilities and military chiefs last night.

Reacting this morning, Sir Keir described reports of the bombing raids as 'concerning' and urged all parties in the region to 'step back and reduce tensions urgently'.

He added: 'Escalation serves no one in the region.

'Stability in the Middle East must be the priority and we are engaging partners to de-escalate. Now is the time for restraint, calm and a return to diplomacy.'
