The moral and intellectual vacuum at the heart of Labour's Middle East policy was laid bare yesterday in a BBC interview with the Foreign Secretary.

Eight times David Lammy was asked whether he believed the US bombing of Iranian nuclear facilities was right and lawful. Eight times he gave the same reply: 'We were not involved.'

Sir Keir Starmer has been similarly reluctant to back America's dramatic intervention, saying: 'All of my focus is on de-escalation.'

They no doubt hope that by sitting on the sidelines of this unfolding conflict, the Government will avoid any collateral damage in the form of terror attacks on British interests.

They may also think that not explicitly endorsing actions of the US, and by extension Israel, will pacify the many hard-line anti-Zionists in their party's ranks.
