Sean Woodcock has been named as the youngest mayor on record at Banbury Town Council.
The 28-year-old is the youngest person to hold the role since the town council started records in 1974.
He had his official inauguration ceremony at the Town Hall on Tuesday.
The social housing worker is thought to be one of the youngest people in the country to hold the position, along with Joe Harris who was first elected as the Mayor of Cirencester aged 20.
First elected as a councillor for Banbury Ruscote ward in 2012, Mr Woodcock is the leader of the opposition on Cherwell District Council.
