 MP Christine Boutin's resignation in 2009 precipitated a by-election, which was won by UMP candidate Jean-Frédéric Poisson with a lead of just five votes over Greens candidate Anny Poursinoff.An appeal and recount led the Constitutional Council to first declare Poisson had won by just one vote, and then ultimately to order a fresh by-election which was held on the 4th and 10 July 2010.Poisson and Poursinoff again advanced to the second round, and Poursinoff was elected with a clear lead of 1,005 votes.
