Marine Le Pen, long-time leader of France’s far-right National Rally and presidential hopeful, goes on trial in Paris on Monday accused of misusing European parliamentary funds.

More than 20 other senior figures in the party are also facing the same charges. They are accused of hiring assistants who worked on party affairs rather than for the European parliament which paid them.

If Le Pen is found guilty, she could face fines and imprisonment – and potentially be declared ineligible to run for office for up to 10 years, hitting her presidential ambitions.
