And just to mix briefs even further, Dr Stephen Ladyman has responsibilty for road safety issues, another part of the DfT which impinges on cycling.

Ladyman likes football, renovating his house and golf.
Twigg likes hill walking, military history, particularly WWII, Rugby League and football.
Neither the DfT website nor Ask Aristotle carry any interests for Buck.
