Leavers and Remainers came together at Ditchley Park over the weekend to discuss the failings of Brexit.

Ditchley Park was used as the “secret” location for cross-party talks to discuss why Britain had not fully taken advantage of Brexit, the Observer revealed on Saturday.

Michael Gove, the Levelling-Up Secretary and a governor of the park, attended the summit and was joined by senior members of Sir Keir Starmer’s shadow cabinet; despite previously co-leading the Vote Leave campaign in the 2016 referendum campaign.

Ditchley Park is a country house in Chipping Norton and was used by Winston Churchill as a weekend retreat during World War II.

The UK’s former chief Brexit negotiator Lord Frost suggested this meeting was part of a “secret” plot to undermine the Brexit agreement which he negotiated.

Lord Frost said the meeting was simply “a further piece of evidence that many in our political and business establishment want to unravel the deals we did to exit the EU in 2020 and to stay shadowing the EU instead”.

Lord Frost told the Daily Mail: “That’s why so many of those responsible for Theresa May’s failed backstop deal were there, while I and those who actually delivered the Brexit agreements were not.”

He continued: “Brexit doesn’t need ‘fixing’.

"It needs this Conservative Government, elected with a huge mandate on a Brexit programme, to fully and enthusiastically embrace its advantages instead of leaving the field to those who never wanted it in the first place.

“I and millions of others want the Government to get on with that instead of raising taxes, deterring investment and pushing public spending to its highest level for 70 years.”

Sources with knowledge of the meeting played down the event’s significance, with one describing the meeting as a “quite dull conference” on foreign affairs.

A Labour source added: “This was a bog standard Ditchley Park conference. Their events are always cross-party.”

Mr Gove has no role in setting Brexit policy in his role as Levelling-Up Secretary.

The UK and the EU recently reiterated their commitment to finding “joint solutions” to differences surrounding the Brexit Northern Ireland Protocol, which was signed in 2019 and seen at the time as a route to unlocking the Brexit logjam.

There is increasing speculation that a deal is on the table to reduce the red tape on trade between Great Britain and Northern Ireland.
