Justice Secretary Jack Straw has hinted that the government may not go ahead with plans to build huge new so-called "Titan" jails in England and Wales.
Gordon Brown says plans to build new huge so-called "Titan" prisons "will go ahead... after consultation", rejecting suggestions in the Commons of a U-turn.
Mr Straw told the BBC: "We're not definitely going to go ahead."
Justice Secretary Jack Straw had earlier raised doubts over plans for new 2,500-place prisons in England.
It came as Chief Inspector of Prisons Anne Owers warned in her annual report the system was at breaking point.

She attacked the Titan plans, saying a building programme should not supersede re-offending schemes, reform of women's jails, probation and mental health.
