More armed police set to protect London

More armed police are to patrol London, Metropolitan Police commissioner Sir Bernard Hogan-Howe and Mayor of London Sadiq Khan have said.
Sir Bernard announced the move to reassure the public and deter attackers following terrorist attacks in Europe.
The Met has already said the number of armed officers will go up 600 to 2,800.
But Steve White, chairman of the Police Federation of England and Wales, said it may take two years to train the 1,500 recruits planned nationally.
