LONDON (Reuters) - Prime Minister Theresa May believes that her Brexit proposal is the “only credible and negotiable plan” for Britain to leave the European Union and that it can get the support of parliament, her spokesman said on Monday.

“The proposal which we have put forward is the one which we believe is negotiable and which can carry the support of the House of Commons,” he told reporters.
