Senior police chiefs and MI5 have warned Labour's plans to release prisoners early could be of 'net detriment to public safety'.

The heads of the Metropolitan Police, MI5 and National Crime Agency were among those who used a letter to the Ministry of Justice to raise their 'collective concerns'.

According to The Times, the letter demanded the 'necessary resources' in Chancellor Rachel Reeves' upcoming spending review to deal with the impact of the plans.

'We have to ensure that out of court does not mean out of justice, and that out of prison does not mean out of control,' it stated.

The Government-commissioned sentencing review, published last week, recommended measures to tackle prison overcrowding.
