The election agreement between the Co-operative and Labour Parties means that 30 candidates can stand as "Labour Co-operative" candidates, and get money for election expenses from the Co-operative Party. There are many other Labour MPs who are Co-operative Party members but are not sponsored. One of these was Gareth Thomas MP, chair of the Co-operative Party since 2001 and of the Co-operative Congress in 2003, who was invited to join the parliamentary group in 2003. The Party has not registered a logo with the electoral commission for use on ballot papers, as candidates use the Labour Party "Rose" logo. Under UK law a party and a logo must be registered if either are to be used on a ballot paper in an election
