The brother of Guantanamo detainee Omar Deghayes was surrounded by police as he protested outside the Labour club where Tony Blair announced his resignation.

Abubaker Deghayes made an anti-Blair statement wearing an orange boiler suit outside Trimdon Constituency Labour Club in Sedgefield today.

His brother has been held in Pakistan and Guantanamo Bay for more than five years without charge.

Abubaker, who runs the Al Quds mosque in Dyke Road, Brighton, said the US detention camp would be a damning legacy for Mr Blair.

He said: "I am here to see Tony Blair off and to remind him of his terrible legacy of the Iraq war.

"Even to demonstrate here we have been escorted by the police.

"We were stopped and searched for no reason whatsoever just to come here and express our right to say that this war is not in our name."

Abubaker and his wife Luci Carolan said they had been followed since 4pm yesterday by police.

They stayed at the Dun Cow Inn on Wednesday night, where Mr Blair famously took President Bush for lunch in November 2003, before making their way to Trimdon.

As Mr Blair announced his resignation and said he had been very lucky to lead "the greatest nation on earth" dozens of protesters joined the media outside.

Abubaker said: "We want to make sure that he knows we will hold him responsible for the injustices of Guantanamo for the rest of his life.

"The have held my brother for five years and he has still not been formally charged or tried for any crime.

"Mr Blair's legacy is taking away our liberties, supporting George Bush, breaking international law and killing thousands of Iraqi civilians.

"Maybe one day he will be tried for war crimes?

"But more than anything else we want to remind him we want my brother back. This isn't just a personal issue, it's a global one."

Omar, a Saltdean law student and Libyan national, was arrested in Lahore, Pakistan, in 2002 before he was transferred to Guantanamo Bay.

His supporters want him to be returned to Britain rather than Libya, where they claim his life would be in danger.

The Save Omar campaign is petitioning Brighton Kemptown MP Des Turner to travel to the USA and plea for his release on their behalf.

Representatives of the Church of England, Brighton and Hove Muslim Forum, the Green Party, the Labour Party and Respect met Mr Turner recently to discuss how to secure Mr Deghayesí release to Britain.

In March, British prisoner Bisher al Rawi was released after MP Ed Davey petitioned for his release in Washington.

Mr Turner said he would consider making a similar trip to the US but said his Parliamentary duties came first.
