From the BBC:
Lib Dems get 'youngest' president
A 12-year-boy has made political history and become one of the youngest-ever local party presidents.
Oliver Smith joined Amber Valley Lib Dems in Derbyshire when he was eight. He
became their president on New Year's Day after being elected in November.
He succeeds out-going president Keith Falconbridge, who being in his mid-50s, is more than four times his age.
He said he wanted to go straight into the adult section of the party in order to make a difference.
“Ollie will shortly have to start GSCE coursework," [his mother] said. "The spark of the idea for him to become president from me and we discussed it at length. We decided that later on he'd be snowed under with GCSE work and sooner was better than later.
"He's very keen to get rid of Mr Blair and Mr Brown as soon as possible - this is one of his campaigning interests."
For some reason, the punchline (verse 9) to Psalm 137 comes to mind.
