Campaigners say elderly or disabled people will suffer

Former Postmaster General Tony Benn MP, singer Damon Albarn and Angela Rippon are among famous residents backing the Notting Hill campaign.

They want to save the Westbourne Grove post office, but have drawn up a report to back a potential legal challenge to the post office closure programme.

It will be handed to Post Office and Postwatch officials on Wednesday.

The closure programme began four years ago in an effort to restructure the Post Office by closing 3,000 urban branches and modernising others.

We have got a case to take this to the High Court, so they are going to have a fight on their hands Dominique Radclyffe, campaigner

Ministers say 95% of urban residents will still be within a mile of a post office.

But the North Kensington and Notting Hill Post Office Closure Action group say many elderly or disabled people will have difficulty getting to another post office.

And they say they have made a legal challenge to the programme based on competition and human rights legislation.

Spokeswoman Dominique Radclyffe told BBC London: "It is our contention the Post Office is acting in abuse of its dominant position.

"We have got a case to take this to the High Court and the European Court of Justice in Brussels, so they are going to have a fight on their hands."

The group is made up of 10 people, but says it represents the 10,000 people in Notting Hill and North Kensington who have signed its petition.

The report will be handed over to Kay Dixon, chairwoman of watchdog Postwatch Greater London, at Powis Square in west London at 1100 BST.
