<P> All political parties have membership schemes that allow members of the public to actively influence the policy and direction of the party to varying degrees, though particularly at a local level . Membership of British political parties is around 1% of the British electorate, which is lower than in all European countries except for Poland and Latvia . Overall membership to a political party has been in decline since the 1950s . In 1951, the Conservative Party had 2.2 million members, and a year later in 1952 the Labour Party reached their peak of 1 million members (of an electorate of around 34 million). </P> <P> The table below details the membership numbers of political parties that have more than 5,000 members . </P> <Table> <Tr> <Th> Party </Th> <Th> Members </Th> <Th> Date </Th> </Tr> <Tr> <Td> Conservative </Td> <Td> 149,800 </Td> <Td> December 2013 </Td> </Tr> <Tr> <Td> Green Party of England and Wales </Td> <Td> 53,000 </Td> <Td> 26 August 2016 </Td> </Tr> <Tr> <Td> Labour </Td> <Td> 528,180 </Td> <Td> 31 March 2017 </Td> </Tr> <Tr> <Td> Liberal Democrats </Td> <Td> 108,000 </Td> <Td> 16 October 2017 </Td> </Tr> <Tr> <Td> Plaid Cymru </Td> <Td> 8,273 </Td> <Td> July 2016 </Td> </Tr> <Tr> <Td> Scottish Green Party </Td> <Td> 9,000 + </Td> <Td> 9 June 2015 </Td> </Tr> <Tr> <Td> Scottish National Party </Td> <Td> 114,221 </Td> <Td> 16 October 2015 </Td> </Tr> <Tr> <Td> UK Independence Party </Td> <Td> 32,757 </Td> <Td> 11 November 2016 </Td> </Tr> </Table> <Tr> <Th> Party </Th> <Th> Members </Th> <Th> Date </Th> </Tr>
