The son of Jeremy Corbyn’s top election strategist said the Manchester suicide bombing had come at an “unbelievably ideal time” for Theresa May, according to reports.

Jack Murray, whose father Andrew Murray was recently installed as Mr Corbyn’s election chief, wrote on Facebook that the media would be “entirely focused” on the attack rather than the “disastrous” Tory campaign.

However, Labour has moved to disassociate itself from the comments by pointing out that the 30-year-old has never worked for the party or held any position.

Earlier this month Andrew Murray, a former member of the British communist party who once called Isil's victories a "series of sudden and stunning triumphs", was brought in to run Labour’s campaign earlier this month having only joined the party in December.
