Another minister who is hardly a household name is our new solicitor general, the barrister and Hertfordshire Conservative MP Oliver Heald.

This is a bit unfair as Heald is one of the very few shufflees to have ministerial experience. As a junior minister in the (then) DSS under John Major, he introduced the shortlived Insurance Companies (Reserves) Act 1995, which was repealed by statutory instrument in 2001. Heady stuff.

He may be a dark horse, however. In his constituency blog on 20 January this year, Heald entered the politically charged debate over airport policy by backing the Thames Estuary scheme. ‘Boris Johnson has taken a bold lead,’ he said, in implicit contrast to Downing Street’s dither.
