May herself will also have a chance to update the other 27 European Union leaders on her Brexit plans at a summit in Brussels on Thursday. But the government will double the length of the session to let lawmakers debate Britain's approach to Brexit without interruption.
Britain's June 8 general election is still casting a long shadow over the entire Brexit process, and although Mr Davis insisted the government was ready for the scheduled talks, the United Kingdom has yet to explain its end goal, or its plan to achieve it. Officials in Brussels fear that their negotiations could be in vain if the objectives are eventually overturned, or if the government's under-staffed Brexit Department is unable to process the negotiating demands.

Mrs May had sought to negotiate a future trade deal alongside the departure terms, but Mr Barnier insisted that the talks follow a clear sequence, dealing with the exit arrangements first.
