LONDON (Reuters) - British Prime Minister Theresa May is expected to make a statement at around 12.00 p.m. ET on Wednesday outside her office after meeting senior ministers to discuss her Brexit deal, a Downing Street official said.

May must convince ministers to back the plan amid open hostility from some of her own members of parliament who say it threatens the United Kingdom’s unity.
