Singer Pete Doherty has been jailed for six months for possessing cocaine.
The 32-year-old was charged after an inquiry into the death of filmmaker Robin Whitehead in January 2010. He pleaded guilty to possessing drugs.
Ms Whitehead was making a documentary on Doherty when she was found dead in a flat in Hackney, east London.
Doherty, of Camden, north London, was due to be playing Glasgow Barrowland on Friday evening.
Last year, the singer said he was “shocked and saddened” by Ms Whitehead’s death.
He has twice been jailed after admitting drugs offences.
