Everyone over the age of 18, in some cases aged 16+, can vote in different elections such as UK general Elections, Scottish Parliament Elections, local council elections or in referendums on important national issues
Members of the public may choose to join a political party such as the SWP, contribute money to the party's funds and support the party during an election campaign
If you support a political party strongly, you could explore the possibility of standing for election for that party to become either an MP, MSP or councillor. If you do not support any political party strongly, you could stand for election as an independent candidate.
This could involve being part of a protest march or demonstration, communicating with an elected representative or sending an e-mail to a local or national news newspaper about an important issue
