Jo Swinson, LibDem MP for East Dunbartonshire, revealed in last Friday's Liberal Democrat News that her travel expenses skyrocketed after a mere year in the House of Commons. But it was not down to troughing. It was just that her young person's railcard expired!
Jo is Britain's youngest MP and was just 25 - therefore qualifying for the railcard - when she was elected in 2005.
Seriously, she reveals some more background to the exposure of Snoutgate on her blog.
