Defence Secretary Ben Wallace has revealed his support for cabinet colleague Liz Truss in the Tory leadership race.
Mr Wallace described Ms Truss as "authentic, honest and experienced", and with having "integrity" for the top job.
"What you see is what you get with Liz and that is what the public wants more than ever at this moment," he told The Sun.
"I've sat next to Liz in the Cabinet for two and a half years. I've sat next to her in National Security Councils. I've sat next to her at NATO and international summits. I've seen her in action."
He also took aim at Rishi Sunak and his resignation from Boris Johnson's cabinet, adding: "I don't have the luxury as defence secretary of just walking out the door - I have roles in keeping this country safe.
"And the guardian of the markets, you know, the guardian of our economy, is the chancellor."
