Tory Chief Whip Andrew Mitchell loves cycling. And shouting. But not the police.
These three facets of his personality collided rather publicly this morning when he launched into a tirade of abuse at police outside Downing Street who made him get off his bike.
Whilst admitting that he did not treat the police with the respect that they deserve, Mitchell denies eloquently describing them as "f**king plebs".

In homage to Mitchell - and as if we needed an excuse - the HuffPost UK has decided to bring to you a selection of MPs going mental.
Enjoy.
