Sadiq Khan's first public engagement since being installed as Mayor of London on Saturday will be at a Holocaust Remembrance Day ceremony.
Mr Khan will appear at the event in Barnet, north London, alongside a number of prominent figures in the Jewish community to commemorate the millions slaughtered during the Nazi genocide.
Up to six millions Jews are known to have been killed in the Holocaust during the Second World War.
The appearance comes after Mr Khan took a strong stance against anti-Semitism during the racism scandal which engulfed the Labour Party in recent weeks.
Labour must reach beyond its own activists if it wants to win elections, Sadiq Khan has warned.
