Sunak urged to stop Braverman speaking alongside far right at Brussels convention

Former home secretary will rub shoulders with populist right from across the globe, including Hungarian prime minister Viktor Orban

Rishi Sunak is being urged to stop his former home secretary from attending a rightwing convention featuring figures who have been under investigation for extremism, in the latest sign of his waning control of his party.

Suella Braverman, who has been a central plotter against the prime minister since she left the cabinet, is set to be one of the keynote speakers at the National Conservatism (NatCon) conference in Brussels this week.
