Elsewhere on the debate, an
interview was broadcast of radical preacher Anjem Choudary with Nick
Ferrari who was hosting the debate with Anne Diamond.
Choudary warned Britain that the death of Fusilier Lee Rigby may not be a one-off shock incident.
The extremist Muslim cleric said "there will be other Lee Rigbys" on UK shores.
Choudary said: "Afghanistan is not occupying Britain. Britain (sic) are going to Muslim countries and killing people.
"This will have repercussions in this country and unless we wake up to this fact, there will be other Lee Rigbys."
The father-of-one, 25, was murdered by Michael Adebowale, 22, and his accomplice Michael Adebolajo, 29 near Woolwich Barracks last May.
They were found guilty of murder last December and will be sentenced on February 20.
He was referring to results of a YouGov poll commissioned for The Big British Immigration Row: Live.
The exclusive research found out that 70 per cent of Britons want immigration to be reduced or stopped completely in the UK.
Choudary said: "There is a fear factor - that the foreigner is causing trouble for them".
He blamed the recession for this attitude and felt Britons thought that immigrants were putting a burden on the National Health Service.
