WPP is also bidding for Dutch agency MediaMonks, pitting the group against its former chief executive, Sir Martin Sorrell.
After very publicly pulling out of all marketing and awards shows last year to focus on Marcel, Publicis Groupe has seen fit to issue an explanation about its presence at this year's Cannes Lions Festival.
Publicis Groupe has unveiled its much-anticipated AI-powered platform Marcel at its VivaTech event in Paris.
Most WPP staff were stunned by the news that Sir Martin Sorrell is facing an investigation into his personal conduct and use of company assets.
The network under Publicis Media will use the brand line, 'Truth. Connection. Wonder.'
The ads will also identify any available ad space and place new ads there, potentially increasing revenue.
