The Inter-Parliamentary Union (IPU) and parliaments around the world celebrate the third International Day of Democracy on 15 September 2010.
The International Day of Democracy was first declared by the United Nations General Assembly in 2007.
This year's theme is political accountability, strengthening links between politicians and citizens.
Here are just some of the ways you can get involved with the work of the UK Parliament:
The public can petition the House of Commons to make MPs aware of their opinion on an issue and to request action.
Lobbying is the practice of individuals and organisations trying to influence the opinions of MPs and Lords. Methods of lobbying vary and can range from sending letters, making presentations, providing briefing material to Members and organised rallies.
UK residents and overseas visitors may watch debates for free on current issues or proposed new laws in both Houses by visiting the public galleries.
Parliamentary Outreach spreads awareness of the work, processes and relevance of the institution of Parliament, encouraging greater engagement between the public and the House of Commons and House of Lords.
Parliament is open to all members of the UK public and overseas visitors. You can attend debates and watch committee hearings, tour the buildings or climb the famous Clock Tower and see Big Ben.
If you can't visit Parliament in person, we've developed a number of different ways for you to take a tour online.
