Is Carla Bruni against a political comeback for Sarkozy?

Le Parisien reports that Carla Bruni "had a huge row" with Nicolas Sarkozy during a holiday in Bali over the former president's ambitions to make a political comeback. Elsewhere in the media, rumours of a disagreement within the former first couple are thought to be part of a narrative being spun by Sarkozy's team. His running for the leadership of the UMP party and thereafter the presidency would be done out of a sense of "moral duty", even if it's against the will of his family.
