THE Westminster leaders of a the SNPLib Dems, Plaid Cymru, SDLP, Green Party and Alliance Party have written to Boris Johnson calling for Dominic Cummings to be sacked.

They call on the Prime Minister to act “without further delay” after his top adviser drove more than 150 miles with his family to Durham during lockdown.

Johnson has stood by Cummings, insisting he “acted responsibly and legally and with integrity”.

The letter to the PM reads: "It is now a matter of record that Mr Dominic Cummings broke multiple lockdown rules.

"He is yet to express any apology or contrition for these actions. There cannot be one rule for those involved in formulating public health advice and another for the rest of us.

"This is an issue that transcends politics. It has united people of every party and political persuasion, who believe strongly that it is now your responsibility as Prime Minister to return clarity and trust in public health messaging.

"We are clear that this can now only be achieved by removing Dominic Cummings from his post without further delay."
