Britain's most senior traffic policeman is to be prosecuted for speeding, his force has said.

Meredydd Hughes, head of roads policing for the Association of Chief Police Officers (ACPO), was allegedly caught driving at 90mph in a 60mph zone in North Wales while on holiday last May.

A spokeswoman for South Yorkshire Police said: "Chief Constable Meredydd Hughes has received a notice of prosecution in respect of an alleged driving offence in North Wales in the early morning of a bank holiday Monday in May while on holiday.

"No summons has yet been received."

The force has not given any indication whether Mr Hughes intends to fight the prosecution.

North Wales Police said it would not confirm any details on a case before it went to court.
