Liz Longhurst:

Jane Longhurst's body was hidden in a unit at the Big Yellow Storage Company, in Brighton, by murderer Graham Coutts.

Liz Longhurst has said an advert which shows a man being locked in a storage unit similar to the one Jane's body was hidden in should be taken off air.

A Big Yellow Storage Company spokesman apologised if the advert caused offence but said it was made before the murder.

It is insensitive. Do it in a year's time but not now Liz Longhurst

He said the unit Miss Longhurst's body was kept in and visited 10 times by Coutts had been sealed up as mark of respect.

The advert, which shows a couple arguing as they load their belongings into a unit, was meant to be "light-hearted".

The man in the advert is heard to say: "Imagine what you can store in here", before the woman locks him in.

Mrs Longhurst, who lives in Reading, has asked the company to pull the advert to give her time to recover.

She said: "It is insensitive. Do it in a year's time but not now.

"I am very surprised they did not instantly remove it after the trial. I'd like to see it taken off the air."

The company spokesman said: "This commercial was made in 2002 and designed to be light-hearted and show how our facilities can be used.

"We could never have anticipated the tragic events of the last months.

"We deeply regret anyone should be offended."

Graham Coutts, who spent hours surfing the web for images depicting severe sexual violence against women in the run-up to Miss Longhurst's murder, has been sentenced to life in prison.

Internet restriction campaign

Mrs Longhurst is now also trying to have tougher restrictions imposed on explicit internet porn.

Her campaign is being supported by Reading West MP Martin Salter who has launched a Commons motion calling for government action to close down extreme sites.

Mr Salter said: "Our campaign in support of the Longhurst family has really taken off with 100 MPs signing in the first 48 hours and an offer from the home secretary to meet myself and the family in the next couple of weeks.

"We shall be pressing the government to draw a clear distinction between images which are simply designed to titillate and those that encourage people to commit harm or even murder others in the name of sexual gratification."
