The sudden death of trade union leader Bob Crow brought tributes from supporters of both Israel and the Palestinians.
Mr Crow, who was leader of the RMT union, had in the past been criticised for anti-Zionist tendencies.
Last year, he encouraged Uefa, Europe’s football governing body, to drop Israel as the host of the under-21 European Championships.
But Mr Crow, who was 52 and died on Monday evening, had also won praise for his efforts on behalf of Israeli unionists.
