Dorries told GB News this week's reshuffle wasn't the work of Sunak, alleging the appointment of David Cameron was instead overseen by the PM’s friend and mentor, William Hague.
Nadine Dorries has launched a scathing attack on Rishi Sunak, asking: "What's the point of having [him] as Prime Minister?"
In an interview with GB News, the former minister claimed he hasn’t made a single decision since becoming Prime Minister.
Speaking the day after this week's reshuffle, Dorries mocked the PM, claiming he won’t make a decision without the say-so of his adviser Dougie Smith.
She said this week's reshuffle wasn't the work of Sunak, alleging the appointment of David Cameron was instead overseen by the PM’s friend and mentor, William Hague.
Speaking days after the launch of her book, The Plot, Dorries told GB News: "When is Rishi Sunak actually going to make a decision? What is he doing as Prime Minister?
"He came into the party and people were told seven years ago that he was going to be Prime Minister.
“But he's never made a decision since he got there because these people have taken him there and they control him.
“And even now, today, he still didn't get to make the decision over who was going to be in his Cabinet. William Hayes (has) just done it."
She added: "So what is the point of having Rishi Sunak as Prime Minister?
"Why don't we have William Hague or why don't we have Douglas Smith?
"These people make all the decisions. Rishi Sunak doesn't doesn't make the decisions.
"He doesn't move without first of all, Dougie Smith saying he can or making a decision unless Dougie Smith approves it.”
Sunak conducted a reshuffle earlier this week, which saw Suella Braverman sacked as Home Secretary, and replaced by James Cleverly.
Cameron was brought back into Government to replace Cleverly as Foreign Secretary in a shock move by Sunak.
The reshuffle also saw Environment Secretary Therese Coffey step down, saying in her letter it is time to "step back", with former Health Secretary Steve Barclay replacing her.
Victoria Atkins stepped into Barclay's old role in the Department of Health, while Richard Holden has replaced Greg Hands as party chairman.
Speaking ahead of the reshuffle, a No10 source told GB News that Rishi Sunak "wants a united team to deliver the changes this country needs for the long term."
