French tax inspectors have concluded that Labour Minister Eric Woerth did not abuse his position to interfere in the tax affairs of France's richest woman, the budget ministry said in a statement on Sunday, according to Reuters. A statement from Budget Minister Francois Baroin said France's General Inspectorate of Finance had also found that information received by the ministry did not justify ordering a tax audit of L'Oreal heiress Liliane Bettencourt's affairs. Woerth is leading President Nicolas Sarkozy's pension reform. He was campaign treasurer at the time of alleged illegal donations by Bettencourt and her late husband to conservative politicians. Woerth has denied any wrongdoing.
