Boris Johnson today backed calls for a memorial in Woolwich to honour murdered soldier Lee Rigby.
London's mayor dismissed fears a permanent monument might become a magnet for extremists. Local Labour MP Nick Raynsford has warned a memorial could attract "undesirable interest" or become a target for vandals.
Greenwich Council said it was trying to establish the wishes of Fusilier Rigby's family following a number of "bogus" calls for a memorial.
Boris Johnson said he was in favour of a memorial.
