Shown through:
Two important bodies that serve PMs; PM's Office, (includes Policy Unit), & Cabinet Office (has developed into coordinating centre of the UK executive) --> PM's office staffed by civil servants and spads, and its influence was increased under Blair
Civil servants, and spads to help with policy advice; PM can work more independently from Cabinet, exerting greater influence
Structural changes by Blair in 2001 means number and significance of Spads who are responsible directly to the PM has increased largely (i.e. Major 8 spads, Blair 50 spads, & Blair was first PM to give senior spads formal control over civil servants)
