LONDON (Reuters) - British Prime Minister Theresa May promised on Monday to be more open with parliament in negotiating the future relationship with the European Union and to ease the concerns of lawmakers over the divorce deal to win their agreement.

Highlighting three changes to her Brexit approach, May told parliament she would be “more flexible”, implement a demand from opposition Labour on guaranteeing workers’ rights and would find a way to calm nerves over a commitment to no return to a hard border on the island of Ireland.

“In doing so we will honor the mandate of the British people and leave the European Union in a way which benefits every part of our United Kingdom and every citizen of our country,” she said.
