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.

Who lobbies Parliament?

Anyone can lobby an MP or Lord. Examples are:

  • individual members of the public
  • groups of constituents
  • local businesses
  • organised pressure groups/campaigners
  • commercial organisations

Does lobbying get results?

MPs and Lords are the target of many different lobbying interests. Often the result these lobbyists are seeking is for the MP or Lord to vote a certain way on a specific issue. However, this decision will ultimately be down to the MP or Lord's own judgement and the influence (if any) that existing party policy will have on them.

Who do I lobby?

A good place to start is with your local MP. You can use our Find your MP service if you don't know who your MP is.

Lobbying and petitioning - what's the difference?

On a very simple level, the public lobby their MP or a Lord directly but petition either the House of Commons or House of Lords as a whole.

Lobbying is an attempt to influence the opinions of MPs and Lords on specific subjects.

Petitioning is making a request to the House of Commons to take action on a specific issue, which is presented to the House by an MP, often on behalf of their constituents. There is a procedure for petitions in the Lords but it is very rarely used.
