Security services missed five opportunities to stop the Manchester bomber

Sources last night told The Daily Telegraph that there were two separate bomb factories, with the chemicals mixed in the rented Airbnb flat in Granby Row before the bomb itself was assembled elsewhere.

It was not clear if the second flat had been discovered.

The photographs of the bomb fragments were leaked to the New York Times hours after Ms Rudd had said leaks of intelligence shared with the US authorities had to stop.

It prompted fury in Whitehall, with Ms Rudd and the Attorney General Jeremy Wright understood to be among officials who phoned their counterparts in the US to demand answers.

The Daily Telegraph understands that there is such serious concern about the leak that Theresa May will raise it with President Donald Trump when she sees him at a Nato meeting in Brussels today.

A senior Whitehall source described the leak as “unacceptable” and said the US authorities had been left “in no doubt about our huge strength of feeling on this issue”.

Government sources accused the US of risking “compromising” the investigation by repeated leaks.
