The dramatic collapse of the drugs trial of N-Dubz singer Tulisa Contostavlos yesterday could have a knock-on effect for a Colliers Wood man.

Leon Anderson, of Boundary Road, Colliers Wood was in the dock at Southwark Crown Court alongside Ashley Gordon of Somerville Road, Romford earlier this year after allegedly being stung in a dry run by ‘fake sheikh’ Mazher Mahmood.

It is alleged the pair were targeted by News International’s Mr Mahmood in a dry run for an undercover operation which had seen singer Miss Contostavlos appear in court accused of being a go-between in a drugs deal which she denied.

It was widely reported yesterday that case collapsed after the judge Alistair McCreath told Southwark Crown Court he believed Mr Mahmood to have lied in giving evidence.

Mr Anderson, 27, and Mr Gordon, 22, did not enter a plea and were due to appear in court on June 25 but there was no record at the court of their appearance.

The Crown Prosecution Service (CPS) has confirmed it is considering the implications of the trial on their case and will assess what further action is appropriate after the collapse of Tulisa Contostavlos and co-defendant Michael Coombs’ trial on Monday, July 21. A CPS spokesperson said: "The CPS is considering the implications of what happened in this trial and what further action is appropriate."
