Meanwhile, the candidate who leads the polls for the first round but not for the run-off, far-right leader Marine Le Pen, was stripped of her parliamentary immunity by the European Parliament in a move than is unlikely to impact her image to her voters.
And all opinion polls indicate that the scandal over the terrorist pictures and separate accusations of alleged financial malpractices in her far-right National Front party would make no difference to the lead which she now enjoys in the electoral campaign.

He left that post a year ago to start his En Marche! party, a self-described centrist group.
The top two from the first round proceed to a run-off on May 7, which Macron is now shown winning.
Now that Le Pen has lost immunity, she may face a prison term of up to five years or a fine of 75,000 euros.
According to the latest opinion polls, Le Pen is the front-runner, followed closely behind by the leader of the En Marche!
