Israel’s Ambassador to the United Nations Danny Danon was hosted by the United Kingdom’s Parliament on Tuesday.

In his address to British lawmakers, Danon said that opposition and Labour Party leader Jeremy Corbyn is “an anti-Semite who wants to return Britain to darker periods in its history.”

The ambassador added that “in his actions and statements, Corbyn gives oxygen to incidents of racism by embracing his terrorist friends and encouraging the activities of BDS. Israel stands by the Jewish community in England.”

Corbyn, whose Labour Party’s popularity in the United Kingdom has surged in recent months amid the ongoing uncertainty regarding Brexit, has come under intense criticism for a number of scandals involving anti-Semitism and support for Palestinian terrorist organizations. Anti-Semitism watchdog groups have called on Corbyn to resign.

The Labour leader also vowed recently to recognize Palestinian statehood if his party were to win in the next general election.
