Almost 1,000 troops have been deployed on UK streets after the terror threat level was raised to the highest level, critical, following the Manchester bombing, suggesting an attack may be imminent.

Steve White, chair of the Police Federation in England and Wales, said this releases police officers for other duties.

He told Daily Politics presenter Andrew Neil: "Armed police officers being deployed are not going to prevent further attacks, they are going to be able to respond to the attack."
