DAVID Davis will accuse Theresa May of being “devoid of democracy” in his most blistering attack on her Chequers plan yet.

Speaking in Munich,he will say the Prime Minister is a bigger menace to voters than Brussels by trying to railroad her compromise plan through the Cabinet and Commons.

Likening her to the worst Eurocrats, he will hit out: “The EU is often correctly described as having a democratic deficit. But Chequers is devoid of democracy altogether.”

Mr Davis dramatically walked out of Government in July after Mrs May sprung the soft Brexit plan on Ministers at her country house.

He will add that “for me, the Chequers plan was always a non-starter,” and insist he will unveil his own “more ambitious” plans “shortly”.

The row over Chequers looks set to dominate the Conservative annual conference in just ten days time.

Tory bosses braced for a backlash last night admitted they had “suggested” removing the word from events held at the gathering.

MPs, think tanks and charities host hundreds of talks on the fringes of the main gathering every year.

Tory sources claim those heading to Birmingham next month have been told the word “Chequers” is outlawed from event titles if they want to hold it within the official conference zone.

Conservative HQ denied a formal ban, but were unable to explain why none of the 400 events in their official conference guide contained the word “Chequers.”

They later admitted “suggesting” the word was not used to one organiser by email.

Approved events are listed in a brochure and app and advertised around the conference area.

A former Cabinet Minister told The Sun: “Central office are getting really funny about fringe meetings”.

Another Tory source said: “Anyone who tried to advertise events about Chequers were quietly told it is was a no no”.

The Best for Britain campaign slammed Mr Davis’s planned intervention, saying: "He’s more like the captain of the Costa Concordia, abandoning a ship he steered into disaster.”
