Sir Sadiq Khan was slapped down by a senior cabinet minister today over his demand that Britain immediately recognise a Palestinian State.

The London mayor spoke out publicly yesterday amid growing international concern - and within the top ranks of the Labour party - at the humanitarian crisis in Gaza.

He said that the UK 'must do far more to pressure the Israeli government to stop this horrific senseless killing', as aid groups warned of starvation in the Gaza Strip caused by the IDF aid blockade.

Sir Sadiq warned that there might not be much left of Palestine to make into a state if global leaders do not pressure Israel's prime minister Benjamin Netanyahu to halt the bloodshed.

But Business Secretary Jonathan Reynolds today suggested that recognising a Palestinian state now would be meaningless, as there is no political unity in the area.
