The presidential palace announced yesterday that Cécilia Sarkozy and Nicolas have divorced “by mutual consent” At the same time, Sarkozy is dealing with the first major challenge to his attempts to shake up the French social and economic system.France has ground to a virtual standstill as public sector workers, mainly in transport and electricity, stage a massive strike over a proposed change to their special pension rights. Yesterday’s concurrent strike and divorce announcement is being called "Black Thursday" in France, and will probably come to be known as the day that Sarkozy lost control of the positive news agenda that he’s had since he became president five months ago. Sarkozy’s whole schtick has been his “ironman” persona, a strong, determined and energetic leader that is determined to strong-arm the changes that France desperately needs. But the collapse of his marriage so soon into his presidency, as well as speculation that the marriage actually ended before the election but Sarkozy has been keeping it a secret, will surely make him lose respect with the public.
