The founder of the English Defence League said he has been warned his life is in danger if he leads an inflammatory protest in Luton on Saturday.
Stephen Lennon, 28, claimed he has been issued a so-called Osman warning by Bedfordshire Police and is under police protection.
Mr Lennon said a written warning given to him by police states the Islamic community are "agitated" by the forthcoming EDL demonstration.
The message added: "There is a threat to the life of leader Stephen Lennon. This is likely to be aggravated by the visit to Luton. You would be advised it would more appropriate if you leave the area for the foreseeable future."
Bedfordshire Police, which have been preparing for the demonstration for weeks, declined to comment on Mr Lennon's claim.
The demonstration route takes protesters from High Town to St George's Square where speeches will take place at about 1pm.
A counter demonstration, organised by Unite Against Fascism, will take place at the same time in Park Square, at the other end of the town's shopping centre.
Hundreds of police dressed in overalls and carrying riot helmets, supported by mounted officers and dog units, will be on duty.
Speaking about the demonstration, Mr Lennon, who uses the pseudonym Tommy Robinson, said members do not want violence.
He added: "There will be 200 of our own security stewards present and we should hopefully be able to police our own demonstration. We want it to be peaceful. We want to get our point across. We want our local and national issues at the forefront, not anything else."
