A sixth Conservative MP is calling for the prime minister to quit over the ever-growing list of alleged lockdown-breaking parties in Downing Street, as Boris Johnson is reportedly preparing to strike back by ousting members of his inner circle.
Tim Loughton, former children's minister and East Worthing and Shoreham MP, said Mr Johnson's position had become "untenable" and that his resignation would be "the only way to bring this whole unfortunate episode to an end".

Queensland border checkpoints torn down after two years
As of midnight (1am AEDT), the Sunshine State is re-opened, without any restrictions for domestic travellers entering the state, either by road or by air. They will no longer need to show a border pass or a rapid antigen test. However, the government will maintain a mandate requiring people to be fully vaccinated to be able to enter events and venues.Acting Chief Superintendent Rhys Wildman was at the checkpoint as it was torn down overnight and said this is "an incredible outcome".
'Obfuscation, prevarication and evasion'
Apologising for the "great hurt" caused to his constituents by the claims, Mr Loughton wrote in a Facebook post: "Frankly the issue for me is not how many sausage rolls or glasses of prosecco the Prime Minister actually consumed.
"The reason for my conclusion in calling for him to stand down is the way that he has handled the mounting revelations in the last few weeks.
"Obfuscation, prevarication and evasion have been the order of the day when clarity, honesty and contrition was what was needed and what the British people deserve."
Mr Loughton said that if Mr Johnson does not resign in the "next few days" he knows "what I need to do" - an indication he could be prepared to submit a letter of no confidence in the PM to Sir Graham Brady, the chairman of the 1922 Committee of MPs.
