In an age of nepotistic knighthoods, dodgy peerages and now even returned CBEs, it is easy to understand the general cynicism around the honours system. Too often it is used to reward politicians for failure rather than success, loyalty rather than achievement, and party rather than principle. None of that, however, applies to Jackie Baillie, who will today officially become the first sitting MSP to be invested as a Dame at a ceremony at Holyrood Palace.
