BNP leader on immigration: "Britain is full"
The British National Party (BNP) are calling for an end to immigration from Muslim nations, saying this presents a "deadly threat" to the UK.
The pledge is contained in the party's election manifesto, launched by party leader Nick Griffin in Stoke.
The BNP also plan to give grants to encourage some UK residents to return to "their lands of ethnic origin".
The BNP recently changed their whites-only membership policy after it was ruled unlawful by the courts.
Their opponents say they are extreme and their policies divisive.
The BNP is targeting Stoke, where they currently have a number of city councillors, plus 333 other constituencies as they seek to get their first MP elected to Westminster.
Although they got two MEPs elected to Brussels in last year's European Parliament elections, they received less than 1% of the national vote in the 2005 UK general election.
The BNP are campaigning on a platform of curbing immigration, only allowing new migrants in "exceptional circumstances" and pledging to deport all illegal immigrants.
Mr Griffin said there was only one new commitment on immigration in the manifesto - which would see all citizenship grants approved since 1997 reviewed to see whether they are still "appropriate".
Mr Griffin said the UK was "full-up" and it was time to "close the doors".
The manifesto states "there should be absolutely no further immigration from any Muslim countries, as it presents one of the most deadly threats yet to the survival of our nation".
The party has previously said Islam is incompatible with modern secular democracy.
Mr Griffin said his party would support "decent settled minorities who accept that Britain should remain British".
But Mr Griffin said the manifesto had a "wholly new emphasis" - accusing the media of being "fixated" with immigration - and was focused on rebuilding the economy and employment.
Among other pledges, the BNP wants to leave the European Union, withdraw British troops from Afghanistan and abolish regional development agencies and other quangos.
It calls for restrictions on imports from China to help protect jobs in British manufacturing and avert "economic disaster".
