The family of a man who died in suspicious circumstances at a party attended by Pete Doherty could find out this week whether any charges will be brought against the singer.

Sheila’s Blanco is meeting with Metropolitan police and lawyers on Thursday to discuss the case against the Libertines frontman, his minder Johnny Jeannevol and the party’s organiser Paul Roundhill.

Her son Mark died after falling from the first-floor balcony of a flat in Romford Road, Whitechapel in December 2006.

There was said to have been an altercation between Doherty and Mr Blanco and the singer was later seen in CCTV footage stepping over his dead body.

Ms Blanco is meeting with the Crown Prosecution Service and officers investigating the case on Thursday.

She told the Advertiser the meeting would only be a step in the right direction if the CPS decides to prosecute.

She added: “I took the dossier to them last year. The Met have never seemed interested in this case but I certainly don’t intend to go away.”

There is a chance Ms Blanco will attempt to bring a private prosecution against Doherty and the others but she said she is taking things one step at a time.

Michael Wolkind QC, representing Mr Blanco’s family, told a Sunday newspaper: “Throughout their investigations, the police have suffered a severe allergy to finding crime, even though it is clear Mark was unlawfully killed.

“This week we will find out if they have overcome their shyness to prosecute.”

Ms Blanco has spent thousands investigating the death independently.
