Jeremy Corbyn has called for Nato to be "closed down", it emerged today as defence chiefs warned his comments about the organisation are "weakening western civilisation”.

In footage uncovered by the Telegraph the Labour leader said the military alliance was an "engine for the delivery of oil to the oil companies" and called for it to "give up, go home and go away."

Mr Corbyn on Thursday was criticised after he refused to say whether he would defend a Nato ally if it were invaded by Russia.
