A man accused of a plot to kill Prime Minister Theresa May in a bomb and knife attack on Downing Street has appeared in court.
Naa'imur Zakariyah Rahman, 20, appeared at Westminster Magistrates' Court on terror charges on Wednesday.
The 20-year-old is alleged to have planned to bomb the security gates outside the Westminster residence before attacking Number 10 with a knife and suicide vest in a bid to kill Mrs May.
Rahman has been charged with preparing acts of terrorism and appeared in court alongside Mohammed Aqib Imran, 21, who is accused of trying to travel to Libya for terror purposes.
They were arrested in raids by the Met's Counter Terrorism Command in London and Birmingham on November 28.
Details of the plan were reportedly given to the Cabinet on Tuesday by the head of MI5 Andrew Parker in a briefing in which he revealed that total of nine Islamist terrorist plots have been thwarted in the UK over the past year.
Rahman, of Ballards Lane, in Finchley, north London, is also charged with assisting Imran in terror planning.
Imran, of Ombersley Road, in the Sparkbrook area of Birmingham, is charged with preparing acts of terrorism.
Rahman, who gave his nationality as Bangladeshi-British, appeared in court wearing a grey tracksuit, with long hair.
Chief magistrate Emma Arbuthnot remanded them in custody to appear at the Old Bailey on December 20.
Mr Parker's Cabinet briefing came on the same day that a review of a string of UK terror attacks earlier this year revealed that the Manchester Arena bomber was known to MI5 and his attack, in which 22 people died, could have been stopped "had the cards fallen differently".
