Most Committees have the power to meet formally and travel informally away from Westminster. Some can travel overseas. The purpose of travel is usually to enable the committee to see people, placed and activities in a way that would be impossible, or very difficult to arrange, at Westminster/ Committees that travel capture these benefits in a variety of ways. Sometimes formal oral evidence is taken. Committees can also publish notes of discussions and/or quote from discussions in their reports. The Liaison Committee needs to agree funding for any travel overseas.
