Very sad, but this was expected.
A very important figure in recent British political history for all the reasons you're all aware of: one thing that's worth emphasising is quite how enthusiastic he could get about things. He may have been the only Postmaster General in the history of the position to view it as a worthwhile appointment: a great increase in the artistic quality of British stamps followed as a direct consequence. Seriously. But he was like that about everything.
His attempt to get the Queen's head taken off stamps failed though.
RIP
BBC and the Grauniad both have a good set of photos of his career:
