Esther McVey has revealed she will stand for leadership of the Conservative Party.
The former work and pensions secretary made the revelation on the talkRADIO breakfast show, during a discussion on her new careers advice charity, If Chloe Can.
When asked by host Julia Hartley-Brewer whether she will throw her hat in the ring in a leadership content, Ms McVey said: "I have always said quite clearly if I got enough support from my colleagues, yes I would.
"Now people have come forward and I have got that support, so I will be going forward."
The Tatton MP said the Conservative Party needed a leader who "believes in Brexit", and had "belief in the opportunities" it could bring.

Theresa May has so far refused to name a date she will resign, despite mounting pressure for her to do so.
"It has to be a dignified and graceful departure," Ms McVey said.
"We all know Theresa May is dutiful. She has worked for public service for many years."
Ms McVey, who quit the Cabinet in November in protest at Mrs May's Brexit deal, became the third Tory openly to declare her ambition to be Prime Minister, after Andrea Leadsom and Rory Stewart.
