Piers Morgan slams Dominic Cummings in public spat

Piers Morgan branded the former government strategist “gutless and pathetic” in reaction to a video clip in which Cummings described the Prime Minister as “a joke” when asked for his thoughts on the government’s handling of the Covid pandemic.

The former GMB presenter tweeted: “REMINDER: it was Cummings (and his Muttley, Lee Cain) who ordered the 8-month ban on ministers appearing on @GMB because we were holding them to ferocious account for all the deadly mistakes they were making last year in the pandemic.”

In response, Cummings hit back: “I banned them cos we all had better things to do, like control the fkd [shopping cart], than waste our time on a vain tool shouting angry soundbites and calling it ‘news’.”

The response hit a nerve with the 56-year-old former newspaper editor who hit back: “a) I don’t think you’re in any position to throw around the ‘vain tool’ slur…”

Referring to Cummings’ 260-mile drive to to his parent’s farm during lockdown her added: “B) Good to see you finally admit you stopped me holding ministers to proper account for their failures that cost 1000s of lives. Gutless & pathetic, like your lies over Barnard Castle.”

In response Cummings replied: “Do us all a favour and spend your time s****ing gossip columnists instead of TV news, at least you're an expert in that (clown emoji)”

Piers Morgan has yet to respond.
