Parliamentary Accountability [PDF ebook] 
A Study of Parliament and Executive Agencies

Written by members of the Study of Parliament Group, this book assesses Parliament’s response to the reorganisation of much of the civil service into 'executive agencies’. Chief executives have been given freedom to take operational decisions. Yet Ministers insist that they themselves remain constitutionally responsible for the work of the agencies. After reviewing Parliament’s mechanisms and considering several case-studies, the authors conclude that Parliament has yet to exploit fully the opportunities for greater accountability which the new arrangements provide.
