Although there exist several key differences between political parties and pressure groups, the distinction between the two is often seen to be blurred since some of the parties in the United Kingdom are too small to have the unattainable hope of forming the government, and as such these parties resort to trying to influence the government. Various pressures groups like trade unions used to maintain close links with political parties to an extent that it was practically impossible to distinguish between the two an example being that the United Kingdom’s Labor Party was formed on the basis of the trade union movement, the trade union movement at one time used to provide the bulk of the party’s funding as well as majorly dominate and influence the direction taken by the various party policies (Williams, 1998).
