One of the teenagers who murdered 16-year-old Brianna Ghey has been refused permission to appeal against the length of his sentence.
Eddie Ratcliffe and Scarlett Jenkinson, then 15, lured Brianna to a park in Warrington, Cheshire, on 11 February 2023 before stabbing her to death in a frenzied attack.
The pair were convicted of her murder after a trial at Manchester Crown Court in December last year.
Ratcliffe was jailed for life with a minimum prison term of 20 years but his legal team had asked the Court of Appeal in London for a reduction claiming the trial judge failed to take his "immaturity" into account.
