One of the formal roles of Parliaments is to conduct oversight of government policy. That international financial institutions are third party organisations based outside the country inevitably adds difficulties to this oversight process and there is a possibility of accountability being lost. However, the role of Parliament in holding the Government to account for all its decisions provides a route for parliamentary oversight of the IFIs. With effective oversight of the Government for these decisions Parliament can help address the accountability gap of the IFIs in the international arena. This paper briefly highlights how this could be accomplished within the UK political system.
