Make a note in your diary - "13 November 2005: form new mass party of the working class".
Well, that's the theory anyway.
Sunday will see the Socialist party - which shot to prominence in the 1980s as Militant, the Trotskyist group of socialist infiltrators into the Labour party who took control of Liverpool city council - call for a new mass party "to represent working people".
The signing of the declaration will take place, with deliberate irony (or possibly not), in Room 101 of the University of London Union, as the climax of the Socialist party (not to be confused with the Socialist Workers party, or the Workers Revolutionary party, let alone Respect) conference.
The party currently has only four councillors and two thousand members, so spokesman Ken Smith accepts it's a daunting task, but "less daunting than trying to reform the Labour party from within".
It promises more "big name signings", but since the existing ones include the likes of Unison NEC member Ralph Parkinson, don't get too excited. The one name that may ring a bell outside hard left circles is Coventry councillor Dave Nellist, who did successfully get elected as Militant Labour MP in 1983 and briefly shared a Commons office with the new MP for Sedgefield, one T Blair.
The Socialist party will not be disbanding, however. What it's calling for is a new umbrella group of the left - modelled on the Linkspartei in Germany, which drew together the former Communists of the East and the trade unions - which will serve to unite existing groupings such as Respect "in a federal structure" .
Mr Blair probably isn't losing any sleep over this new challenge from the left, but remember - you read it here first.
