A man repeatedly punched his partner in an “appalling” attack as she drove at a speed of 70mph along the M4 while their children were in the vehicle.
Gareth Davies, who owns a burger van, inflicted injuries to his partner’s face and body, before the car crashed into a hedge at the roadside.
Davies, of Monmouthshire, was sentenced for assault occasioning actual bodily harm of his then-girlfriend and for breaching the conditions of a suspended sentence handed to him last year for assault occasioning actual bodily harm of a previous partner, theft, disclosure of private photos, dangerous driving and possession of cannabis.
