Shares in Cheil Worldwide, the ad agency which is part of the Samsung Group in South Korea, are up following reports that Publicis Groupe is interested in acquiring a stake.

The Paris-based advertising group is considering making a bid for around 30 per cent of the company, according to media reports.

Cheil shares rose as much as 9.1 per cent to Won21,550 on Thursday.

Earlier this month British ad group WPP said it is buying a digital ad agency in South Korea for an undisclosed sum.

Publicis, which also owns heavyweight ad firms Saatchi & Saatchi and Leo Burnett, is looking for ways to boost growth after its much-touted $35bn mega-merger with US rival Omnicom broke down in 2014.
