A terror suspect has denied trying to murder members of the public and police officers in an alleged attack outside the Houses of Parliament.

Salih Khater, 29, allegedly drove his silver Ford Fiesta into cyclists and pedestrians before swerving towards police officers and crashing into a security barrier.

Three people were treated for non-life threatening injuries after the crash.

The Sudanese-born suspect, who is a British citizen, was arrested by armed police outside the Palace of Westminster and was due to stand trial on February 4.

But Mr Justice Sweeney pushed back the trial date to June 24 during a hearing at the Old Bailey on Monday.

Khater, wearing grey tracksuit bottoms and a maroon sweatshirt, appeared by video-link from Belmarsh prison, in south-east London, and remained seated throughout the hearing.

He spoke only to confirm his name before entering not guilty pleas to all charges against him as the four-count indictment was read out in court.

Khater, of Highgate Street, Birmingham, is charged with two counts of attempted murder and two alternative charges of attempting to cause grievous bodily harm.

The charges state he attempted to murder people at the junction of Parliament Square and St Margaret Street and police officers in Abingdon Street on August 14 last year.

Although he is not charged with a terror offence, prosecutors allege Khater carried out a terrorist attack.

Khater was remanded in custody.
