Guido can confirm well known Commons terrace aficionado and the director of the Parliamentary Resources Unit Iain Corby has resigned. Tory MPs have been told:

“I am sorry to have to inform you that, after six successful years, Iain Corby, the PRU’s Director, has decided to move on from the Unit and return to the commercial world.  In his time here Iain has demonstrated excellent leadership, not least around the time of the last election and, since then, in expanding the number of services offered to our subscribers. We wish him well for the future.”
