The Constitutional Council of France approved the redistricting of electoral boundaries in February 2010 to reflect France's changing demographics. The population ratio between the most populated and least populated constituencies was reduced from the 1986 redistricting results of 1:3.6 to 1:2.[1] In effect, the number of seats increased in areas held by the centre-right coalition led by Union for a Popular Movement at the expense of the Socialist-led centre-left coalition.[2] The 2010 redistricting process not only brought down the rule of two deputies per department to one, it also created eleven constituencies for French residents overseas.
