LONDON (AP) — British Prime Minister Theresa May fought back against critics of her Brexit deal Saturday, telling opponents from within her party their alternative plans for Britain’s departure from the European Union wouldn’t work.

May is battling to win over rebels in her Conservative Party and and to preserve her position as prime minister after a grueling week in which party members plotted to oust her and two Cabinet ministers quit within hours of her government striking the long-sought divorce agreement with the EU.
