Lindsay Whittle stood for election in Caerphilly 13 times since 1983 - and on the 14th attempt, he finally succeeded.
In the process, the 72-year-old local boy - nicknamed "Mr Caerphilly" - humiliated the Labour Party , which had held the Senedd seat since its creation in 1999 and the Westminster constituency for over a century.
Born in the miner's hospital, Mr Whittle lived in a council house and grew up in the town, located to the north of Cardiff, that he now represents.
A lifelong Plaid Cymru activist, his interest in politics was first piqued in the 1960s. He said he even missed an O Level (GCSE) exam in the 1970s because he was out canvassing for the party.
