Adonis doomed?

This from Matthew Parris in today's Times (with a bowler tip to Nigel Harris)

As a transport minister, Andrew Adonis is travelling the 2,000 miles of our rail network that he knows least, just to see what's going on. He plainly loves railways, but with technical knowledge and without sentimentality.

Why, after a change of government, can't we keep ministers who really care about their jobs?

If we had more Adonises in British politics, the fungus in Downing Street would never have spread.

That's his ministerial career over then.
