The prime minister is expected to announce a renewed prison-building programme after concerns that previous plans to increase capacity by 10,000 places before 2020 have stalled. During the Tory leadership campaign Mr Johnson also committed to keeping serious sexual and violent offenders behind bars for longer, calling it wrong that they were routinely released after half of their sentence.
The Times has also been told that the Crown Prosecution Service will make an announcement about increasing the number of rape prosecutions, which have fallen to their lowest for more than five years. The number fell from 11,311 in 2017 to 7,594 last year despite a huge increase in recorded sex offences. Prosecutions for all offences have also hit a 50-year low despite rises in the crime rate.
