The House of Lords Constitution Committee to quiz three Ministers this week in the final of a series of evidence sessions of the peers inquiry into the constitutional arrangements for the use of armed force. This week’s session will focus on Parliament’s role in approving decisions to use armed force overseas, bearing in mind that MPs, from all parties, in the past few weeks were pressurising government not to supply arms to Syrian rebels fearing that might become a mission creep with British military involvement in that troubled and troublesome part of the world.
