Johnson appoints foreign secretary to be Brexit negotiator

Prime Minister Boris Johnson has announced the appointment of Foreign Secretary Liz Truss to become lead negotiator with the European Union

LONDON -- British Prime Minister Boris Johnson on Sunday announced the appointment of Britain's foreign secretary to become the country's lead negotiator with the European Union, after long-time ally David Frost resigned after a week political upheaval in the Conservative Party.

Liz Truss will have ministerial responsibility with the EU and will lead negotiations to resolve problems arising from provisions of the Brexit agreement covering trade with Northern Ireland, the prime minister’s office said in a statement.

In his resignation letter, Frost expressed concern about the government’s “current direction of travel.’’

“I hope we will move as fast as possible to where we need to get to: a lightly regulated, low tax, entrepreneurial economy, at the cutting edge of modern science and economic change,’’ he wrote.
