Two Muslim men are suspected of conspiring to attack Downing St armed with an improvised bomb, suicide vest and knives.

Counter-terrorist chiefs said it was the ninth foiled plot since March as hundreds of terrorist suspects remain under investigation.
The security service and police have thwarted 22 terrorist plots in the past four years and there are more than 500 live investigations ongoing.

The head of MI5, Andrew Parker, yesterday briefed Cabinet ministers on the unprecedented terrorist threat facing the country.
Parker has said the threat facing the UK was at the "highest tempo" seen in his 34-year career.
The Prime Minister's spokesman said: "Mr Parker said that nine terrorist attacks had been prevented in the past year. There have been five attacks that got through, four of which are related to Islamist terrorism." May thanked Parker and MI5 for their "tireless work" tackling terrorism.
Some of the foiled terror attacks have never been made public for security reasons, although the majority have.
