The Home Secretary has refused to say if she had been part of effort by Tory MPs to persuade Andrew Mitchell to resign as chief whip.
Asked about the claims, Theresa May told BBC1's Sunday Politics: "I'm not going to talk about private conversations. Andrew has resigned. I think that is an end to the issue."
She also played down the significance of recent headlines, insisting the Government was doing well on issues that mattered to voters. "For voters what matters is what the Government actually delivers for people."
