France gears up for strikes and protests as unions promise national mobilisation

Hundreds of thousands of demonstrators are expected to take part in marches across France as five unions join strikes and protests in a national day of action.

The protests began in September with high school students complaining about poor conditions and resources in education, but have spread to include the so-called "yellow vest" movement and workers.

Authorities expect 500,000 to 700,000 demonstrators to join marches, with tens of thousands more in Paris alone, in a day billed by one union leader as "a great day of convergence".

The five unions have combined forces across the public and private sector, with demands for higher wages to combat the cost of living and protected public services.
