A SENIOR Tory has piled fresh pressure on Nadine Dorries to quit as an MP after failing to speak in the Commons for more than a year.

The former Cabinet minister said in June that she was resigning with “immediate effect” after she failed to receive a peerage in ex-PM Boris Johnson’s honours list.

However, the Tory MP is yet to stand down formally, claiming she is investigating why she was refused a seat in the House of Lords.

Rishi Sunak (below) has already said the former culture secretary’s voters “aren’t being properly represented”.

Now, during an interview with Sky News, immigration minister Robert Jenrick has called on Dorries to quit.

“I think being a Member of Parliament is a special privilege. You sign up for a term in office”, he said.

“If you decide you want to leave Parliament for whatever reason, you need to get on and do that.

“I don’t think that Nadine Dorries’ constituents are being properly represented. I hope she’ll reach that conclusion soon.”

Dorries remains the MP for Mid Bedfordshire but is currently hosting a weekly chat show on Talk TV.

She has also written a book titled The Plot: The Political Assassination of Boris Johnson, which is to be published in September, just days before the Tory party conference.

The Mid Bedfordshire seat has been held by Dorries since 2005 and the Conservative Party generally since 1931.

Earlier this week, we told how Dorries faced criticism after she accused a Labour MP of attention seeking after he spoke out about his experience of sexual assault.
