The British National Party is to launch its General Election manifesto - a week after its leader promised the document would "surprise" voters.
BNP leader Nick Griffin and deputy leader Simon Darby are expected to speak at the event, which is being held at an as-yet undisclosed location in Stoke-on-Trent.
Although the BNP informed Staffordshire Police of the venue for the St George's Day launch, the party declined to reveal the site to the media for security reasons.
A BNP spokesman said the decision not to divulge the venue until shortly before the launch had been taken to preserve the safety of members of the media and others present at the event.
Mr Griffin, who is standing for election in Barking, east London, is among more than 330 BNP candidates contesting the May 6 poll.
Speaking last week, Mr Griffin said of the manifesto launch: "I can promise the public many surprises in the document."
The BNP leader warned earlier this week that Britain would face economic "disaster" unless British jobs were protected from foreign competition.
He said import restrictions should be imposed so that British workers could make goods which would otherwise come flooding in from countries such as China.
A spokesman for Staffordshire Police confirmed that the force had been notified of the launch event.
A small number of local neighbourhood officers would be on duty to facilitate lawful electioneering, the spokesman said.
