Avon and Somerset Police have been asked to look at claims the Merseyside force withheld evidence which could have freed a man convicted of his wife's murder.

Eddie Gilfoyle served 18 years in prison for killing eight-month pregnant Paula in Wirral, near Liverpool in 1992 - but has always protested his innocence.

Detectives here will now review what had happened to a box of evidence - including Mrs Gilfoyle's personal diaries.
