Sir Sean and wife Micheline when he was knighted last year

"But Labour's new laws party funding treat me like a foreigner.

"They prevent people like me from giving a penny to the SNP but do nothing to stop the millions that are flowing into Labour's coffers in London."

Sir Sean is a resident of the Bahamas who also spends part of each year in Spain.

The new law is part of the Political Parties, Elections and Referendums Act, drawn up after concerns about money buying influence following big donations from business people.

It states that exiles who want to fund mainland British parties must have a British address and also be registered to vote here.

'Struggle'

Sir Sean's comments come only a few weeks after he first spoke out against the new funding laws.

In December, he wrote in a Sunday newspaper, saying:

"New Labour - new stitch-up. That's my opinion of the new rules on party funding, rushed through Westminster a couple of weeks ago."

In the past, he has claimed that Labour tried to block his knighthood in revenge for him supporting the nationalists.

He also recently backed calls for the Scottish Executive to be termed a government.

"That gives us a taste of what it would be like if we really did have control over our own affairs in an independent Scotland," he said.

"We have taken the first steps after years of struggle. No-one should fear completing the journey."

Sir Sean was knighted by the Queen in July 2000 at the Palace of Holyrood house in Edinburgh.
