The far right British National Party has called for an end to immigration from Muslim nations saying it presents a deadly threat to the UK.<br/>The promise to stem the flow of immigrants is contained in the BNP's election manifesto launched overnight by party leader Nick Griffin. <br/><br/>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". <br/><br/>The BNP recently changed their whites-only membership policy after it was ruled unlawful by the courts.<br/>
