In the British Labour Party, one sponsored by a trade union which meets a proportion of election and office expenses. In the past sponsorship was important in enabling working‐class candidates to enter Parliament. Nowadays many sponsored candidates have no real connection with the sponsoring union, although they may undertake to liaise with the union. Sponsorship does not permit a union to dictate how a candidate or MP should behave.
Some trade unions and pressure groups such as the police, farmers', and teachers' unions sponsor MPs from all the main parties but do not contribute to campaigning activities.
