The Metropolitan Police was branded 'institutionally racist' after the Stephen Lawrence inquiry

Nobody has been convicted of the murder of Mr Chhokar, who was stabbed to death in Overtown, near Wishaw, Lanarkshire, in 1998.

Three men who admitted being at the scene of the crime were later prosecuted in separate trials, but all were acquitted after blaming each other for the killing.

Ronnie Coulter, 32, from Wishaw, claimed in the original trial in March 1999 that his cousin Andrew Coulter, 19, from Wishaw, and David Montgomery, 23, from Motherwell, were responsible for the killing.

Trial judge Lord McCluskey described the Crown's decision to put only one of the trio in the dock as "extraordinary".

Judicial inquiry

At a second trial in November last year, Andrew Coulter and David Montgomery were also cleared of the killing, although Coulter was jailed for a year for the lesser crime of assault.

Dr Jandoo's inquiry was designed to review how prosecutors liaised with the Chhokar family and address concerns that they were not kept up-to-date with events.

A separate judicial inquiry headed by Sir Anthony Campbell, Justice of the Supreme Court of Northern Ireland, was also launched.

At the conclusion of last year's trial, Strathclyde Police insisted its investigation into Mr Chhokar's death had been "intense, thorough and professional" and maintained the killing had not been racially motivated.

The term "institutional racism" was first used against the Metropolitan Police by the Macpherson inquiry into the death of black London teenager Stephen Lawrence and has been the subject of fierce debate ever since.
