Excerpt:
David Cameron has hailed Labour's Sadiq Khan as "a proud Muslim" and "a proud Brit" as he shared a platform with the London Mayor at an EU Remain rally.
They were launching a Britain Stronger In Europe battle bus and pledge card.
But Vote Leave said the PM's criticisms of Mr Khan during the mayoral contest less than a month ago showed he could not be trusted.
UKIP MP Douglas Carswell said the PM had accused Mr Khan of being a "terrorist sympathiser".
