A "lunatic" who killed three people including his teenage girlfriend in a drink-driving crash is trying to have his prison sentence cut.

Jack Diamond was jailed for seven-and-a-half years after his Volvo estate overturned and collided roof first with a wall in Hawkhurst in 2017.

The driver's partner, Chelsea-Rose Betts, 16, and colleagues at Sandhurst Vineyard, Roy Little, 44, and Stephen Jones, 50, were all killed in the smash on the A268 Rye Road on September 23.

Chelsea’s brother Billy Bartley, then 13, was seriously injured.

Mr Little and Miss Betts lived in Sandhurst and Mr Jones was from North Wales.

Diamond, of The Street, Sedlescombe, near Battle, East Sussex, admitted three offences of causing death by dangerous driving and one of causing serious injury by dangerous driving.

A witness who had seen him leave a pub earlier had described him as driving “like a complete lunatic”.

Diamond was told he would serve three years and three months before being released on licence, however, it has now emerged he is to try and cut his sentence further at the Court of Appeal next week.

Relatives of Chelsea said last year the term handed to him was "not justice".
