 Mayotte became an overseas department of France in March 2011 in consequence of a 29 March 2009 referendum.The outcome was a 95.5 per cent vote in favour of changing the island's status from a French "overseas community" to become France's 101st département.Its non-official traditional Islamic law, applied in some aspects of the day-to-day life, will be gradually abolished and replaced by the uniform French civil code.
