Our international affairs editor Dominic Waghorn is in Paris today.
He’s been speaking on Sky News ahead of the speeches on the rally.
Let’s run through his analysis below:
“We’re told they’ve sold 10,000 tickets to this event right in the heart of Paris.
“[Le Pen’s] been thwarted in her ambitions almost certainly terminally by that shock sentencing.
“What caused the shock, not just among her supporters but among opponents, was that she was banned from running for office for five years, which probably puts her out of the running in the future for leading a party to victory.
“She has a chance to appeal, but the evidence doesn’t look very good.
“It’s a question of where she moves next and where she takes this party that she effectively inherited from her father.
“We’re going to look very closely to see what Le Pen has to say in her speech.”
Worries of clashes
Another thing Waghorn highlighted was fears of violence with so many different demonstrations in the French capital today.
He said: “The centrists are rallying in one part of the capital, the leftists in another and the fear for the police is that at some point these rallies might become a little less static and might start moving towards one another.”
He said there have been some “scuffles” already.
