JOhn Penrose, the government’s former anti-corruption czar, said Boris Johnson was currently “out in the open” with voters and MPs.
The senior Tory MP said the ‘parameters’ of the role of independent adviser on ministers’ interests could be changed, but the role itself should remain.
He told the BBC: “So definitely change the settings, but I don’t think you can weaken it, especially at the moment.
“I just think that the Prime Minister is currently exposed, if I can put it that way, on his account both to the voters and to the parliamentary party.
“They have to show they are serious about it. This is part of the reset, I would say, that the Prime Minister rightly said he wanted to do after last week’s vote of no confidence, good for him. That would be a good way to be a part of that and then push it forward.
