This has gone for too long. @BorisJohnson now has very serious questions to answer about his judgement and integrity. The Prime Minister cannot dodge scrutiny any longer. That’s why I’m calling for him to come out of hiding and face the press at today’s conference.

The public deserve the truth. Boris Johnson must put on record what he knew about Dominic Cummings' rule-breaking and whether he played a role in the Downing Street cover-up, which kept the public in the dark for eight weeks.

It is beyond doubt that Dominic Cummings broke multiple lockdown rules, possibly on multiple occasions. As Scottish Tory leader @Jackson_Carlaw said: “There cannot be one rule for bosses and another for everyone else.” Mr Cummings must go - or Boris Johnson must sack him.

The various contradictory excuses are not credible and do not stack up. There is now a mounting rebellion of Tory MPs who are demanding Mr Cummings go. They understand the lasting damage this is doing to public confidence in the Tory government and its covid-19 response.

The SNP will continue to press for a Cabinet Office inquiry into the breaking of the rules and the Downing Street cover-up. With every hour the Prime Minister allows this farce to continue the Tory government loses more credibility and respect. He should act without further delay
