Public Administration and Constitutional Affairs Committee
Government Response received
The decision to use military force, whether alone or as part on an international coalition is taken by the Government as an exercise of the royal prerogative power.
Parliament has no legal role in authorising the use of military force, however since 2003 Parliament has been asked on a number of occasions to approve the use of military force. This has led some to suggest that the convention governing the use of the royal prerogative has changed to require parliamentary approval.
This inquiry will examine the constitutional underpinning for decisions to use military force.
