Serving officers today claimed Donald Trump is right to say London’s police are frightened in Muslim areas of London despite Scotland Yard saying the tycoon ‘couldn’t be more wrong’.

Several Met officers have said ‘Islamification’ of the capital is happening and revealed they do need to be ‘extra vigilant’ and even abandon using uniforms on some estates.

The US presidential contender Donald Trump caused worldwide consternation after a string of incendiary remarks, including in Britain when he said: ‘We have places in London and other places that are so radicalised that police are afraid for their own lives.’

Scotland Yard hit back last night but one serving officer has said: ‘Islamification has and is occurring’, adding: ‘You have to have extra vigilance in certain parts when you are working’.
