Tom Watson is quitting parliament and stepping down as Labour’s deputy leader, reopening the debate about the party’s direction under Jeremy Corbyn.

Watson, who is one of Labour’s best-known figures, has represented the constituency of West Bromwich East since 2001.

He has repeatedly clashed with Corbyn, including over the Labour leader’s Brexit stance and his handling of antisemitism, and the party’s conference in Brighton in September was overshadowed by a botched bid to abolish his post.
