Labour has retained Bishop's ward on Lambeth Council, with Ibrahim Dogus joining incumbents Kevin Craig and Jennie Mosley representing Waterloo and the South Bank at the town hall.
Lambeth Liberal Democrats had been hoping to retake the ward they lost in 2014 but they missed out by nearly 400 votes.
He is also the publisher of local newspaper Lambeth Life.
Cllr Dogus replaces Cllr Ben Kind who sought election in Tulse Hill ward this time round.
Councillors Craig and Mosley have been prepared to deviate from the Lambeth Labour party line over the past four years, including on the Garden Bridge where they publicly distanced themselves from the administration's backing for the controversial project.
