Senior Tory Michael Gove took part in a “secret” cross-party meeting where the failings of Brexit were reportedly discussed.
The summit, held last week at Ditchley Park country house in Oxfordshire, was attended by high-ranking politicians, diplomats, business experts and Leave and Remain campaigners.
David Lammy and John Healey, two members of Keir Starmer's top team, attended the two-day gathering, according to the Observer.
