Are student protests being manipulated ahead of France's presidential election?

The French passion for protest is legendary in Europe.

Over the last few years, we have regularly witnessed farmers angry about costly regulations lobbing manure at local mayoral offices, while masked youths periodically hurl homemade grenades at riot police in disadvantaged city suburbs.

For over three weeks now, thousands of students have barricaded entry to high schools and taken their grievances to the streets.

This Saturday, hundreds of new demonstrations have been announced across France.

Students are expected to be joined by workers' unions and key figures from the so-called "yellow vest" movement.

France's prime minister, Sébastien Lecornu, suggested this week that student anger was being manipulated as politics heats up ahead of next year's presidential election.

The gilets jaunes (yellow vests) demonstrated against cost-of-living hikes for over a year from 2018 - becoming one of the longest-lived protest movements in French history.

Jérôme Rodrigues, a prominent gilets jaunes activist, has used Instagram to encourage people to join Saturday's demonstrations.

The protests should give a voice to those who "want to be able to live decently, no longer have to count every cent, and no longer have to choose between eating and driving", he said in a video.

"Anger has no political party. An empty fridge has no political party," he added.

So what is going on in the EU's second largest economy?

Social unrest, government borrowing costs at eye-watering highs, a deeply divided French parliament and an apparent revolving door of exasperated French prime ministers - six prime ministers over the last five years - all claiming to want to reduce their country's public debt.

Is France at breaking-point - and what does this all mean for the eurozone currency the French are such a huge part of?
