Razzy Hammadi is elected without opponent in the second round following the withdrawal of Jean-Pierre Brard.

The parties of the mainstream left had a nationwide agreement whereby if two of them advanced to the second round, the second-placed would automatically withdraw.

Primarily, this was to avoid dividing the left-wing or centre-left electorate in constituencies where a right-wing, centre-right or far-right candidate had also reached the second round.

In Montreuil, however, the Communist and Socialist candidates were the only ones to reach the second round, respectively in first and second place.

Socialist candidate Mouna Viprey honoured the agreement and withdrew, enabling Brard to be re-elected in a walkover.
