The Justice Secretary has denied UK prisons are in crisis, despite a rise in assaults by prisoners in England and Wales.
Chris Grayling's comments come as the latest surprise inspection of a facility in London found high levels of violence at the Isis prison with a high population of gang members.
Figures released last month by the Ministry of Justice showed a 6% rise in assaults in prisons in the year ending March 2014, up to 15,033 from 14,083 in the previous 12-month period.
Mr Grayling told the BBC: "We're meeting those challenges, we're recruiting more staff. I am absolutely clear there is not a crisis in our prisons".He added that prison violence "is at a lower level today than it was five years ago".
