Seven British lawmakers say they are quitting the main opposition Labour Party over its approach to issues including Brexit and anti-Semitism.

Many Labour lawmakers are unhappy with the party's direction under leader Jeremy Corbyn, a veteran socialist who took charge in 2015 with strong grass-roots backing.

They accuse him of mounting a weak opposition to the Conservative government's plans for leaving the European Union, and of failing to stamp out a vein of anti-Jewish prejudice in the party.

Luciana Berger, one of those who announced Monday she is leaving, said Labour has become "institutionally anti-Semitic."

The quitters are only a fraction of Labour's 256 lawmakers. But this is the biggest split in the party since four senior members quit in 1981 to form the Social Democratic Party.
