The prosecution is due to open its case in the trial of Tulisa Contostavlos who is accused of brokering a drug deal. The former N-Dubz star, from north London, is charged with helping the Sun on Sunday's undercover reporter Mazher Mahmood obtain 13.9g of a Class A drug for £860.
It is claimed that Contostavlos told Mr Mahmood that she could arrange for him to buy cocaine from her friend Michael Coombs. Yesterday 36-year-old Coombs from Enfield admitted supplying cocaine to Mr Mahmood. Tulisa Contostavlos denies the charge.
