Liaison Committee
The Liaison Committee is a committee comprising all the chairmen of the select committees in the House of Commons.

There are a number of days set aside for debates recommended by the committee.
List System
The List System is a voting system which involves multi-member constituencies, where the elector votes not for individual candidates but for a list of a particular party. Seats in the constituency are allocated between the parties according to their proportions of the vote in that constituency. Seats are allocated to individual candidates according to their position on the party list. Mid-term vacancies are filled by the next candidate on that party's list. The system was introduced for British elections to the European Parliament from 1999.

A lobby is another word for a room that serves as a meeting place. There are several lobbies in the Palace of Westminster which are used by different groups of people.

They are able to talk in private to MPs and Ministers and also meet the Prime Minister's Press Officer regularly. They are very well informed about what is going on in Parliament but they usually keep their sources of information confidential.
Lobbying
Lobbying is the practice of making representations to Members of Parliament and government, by individuals and organisations, in order to change policy and actions.
