The London Mayor's race is "hotting up" (not heating up, as in American English). Each of the candidates, current mayor Ken Livingston (labour) and Boris Johnson (conservative) have issued "transport manifestos".
While Ken Livingstone may now be somewhat well-known to Americans interested in congestion pricing, Boris Johnson is himself a celebrity of sorts in the UK, a British version of a young William F. Buckley perhaps? He manages to attract publicity for whatever he does.
An article on Ken Livingstone's campaign and manifesto are linked to from here:

Boris Johnson's Manifesto can be found here:

One of the major issues is "Bendy Buses" (Articulated Buses), which have in recent years been introduced to London's streets, and are not terribly popular, especially with cyclists.
Johnson has also called for reconsideration of the western extension of the congestion charging region implement in 2007.
