Justice Secretary Alex Norris has been tasked by new PM Andy Burnham with finding ways to keep the serious offenders in prison, including the killers of PC Harper

PC Andrew Harper, a 28-year-old police officer, was killed in August 2019 after responding to reports of a stolen quad bike in Berkshire.

Downing Street said it was 'not possible' to exempt 'one or two offenders' convicted of manslaughter amid an outcry at the possibility of Jessie Cole and Albert Bowers being freed.
