Ken Livingstone has justified his decision to welcome a controversial Muslim cleric to London last year.
Mr Livingstone embraced the cleric at City Hall in July
Egyptian-born Yusuf Al-Qaradawi has been criticised for condoning suicide bombings and having anti-Semitic and homophobic views.
The Mayor of London acknowledged that he and the cleric would not see eye-to-eye on Lesbian and Gay views.
But he said engaging with Dr Qaradawi would help enhance relations between the West and the Muslim religion.
Mr Livingstone told a press conference on Tuesday: "When you get a progressive figure who is moving that religion in the correct direction you engage and you develop it.
'Engage with cleric'
"And I don't agree with the position of Dr Qaradawi on lesbian and gay rights.
"As I said before we won't be seeing him on the next Pride march but here is the force that we need to engage with if we are to actually get a dialogue between the west and the Muslim world."
Mr Livingstone caused controversy when he embraced the cleric at a meeting in City Hall in July.
Leader of the London Assembly Conservatives Bob Neill condemned Mr Livingstone's support for the cleric.
He said: "He is the type of man Mr Livingstone should, like us, be condemning not cosying up to. It's utterly unacceptable."
