Environmental campaigners blocked Downing Street in central London on Monday with a four-metre “oil-splattered” statue of Prime Minster Boris Johnson as they again called on the UK government to reject Siccar Point Energy’s plans to develop the Cambo oilfield.

Staging the protest outside the street containing the UK leader's official residence, activists locked themselves to the stone-effect statue emblazoned with the words “Cambo oilfield: Boris Johnson’s monumental climate failure”.

Philip Evans, oil campaigner for Greenpeace UK, said: “People across the UK are feeling the stresses of a gas price crisis as well as a climate crisis, and the government acknowledges that our reliance on fossil fuels has left the UK vulnerable and exposed.
