Martin Gaillard is a sales executive working in Paris. He’s been living with his American boyfriend for the past eight years, and they plan to get married in New York – where it’s legal. No prizes for guessing what he’d change if he were president.

Suited, booted and briefcase in hand, we manage to catch Martin between meetings at the Saint Lazare train station in the 9th arrondissement of Paris. Martin campaigns for LGBT rights in his spare time, so it’s not hard to get him talking. We even managed to squeeze a few answers out of him in English.

What would you change if you were president?

Could the result of this election change your life?

Which parties are you counting on to legalise gay marriage?

Do you think gay marriage will be a major election issue this time round?

Who do you think gay voters are going to support in this election?

Next week, we meet Tarek Mouadane, a youth-rights activist from the deprived Parisian suburbs who – unlike the majority of his neighbours and peers – supported Nicolas Sarkozy during his 2007 election campaign. Does he still support the “bling-bling” president?
