While the United Kingdom has been reeling from political crisis to political crisis in the aftermath of the Brexit referendum, Jeremy Corbyn has never looked stronger.

He showed his principles in apologizing for a war he opposed from the very beginning, he has consistently made an argument for an anti-austerity, antiracist politics that can fight for all sections of the working class, and he so far appears to have survived a coup attempt on his leadership.

In fact, Jeremy Corbyn, a survivor of “lifeboat socialism,” now finds himself at the helm of what is likely Europe’s largest social-democratic party. Several hundred thousand new members have joined Labour in the past two weeks, largely to support Corbyn against the on-again, off-again coup effort led by a powerful faction centered within Labour’s parliamentary caucus. Yet despite these efforts, Corbyn is one of the few party leaders left standing after the referendum.
