Brazil, Israel, Serbia and the US are holding elections within the space of 10 days. Will the authoritarian right cement its global gains, or can pro-democracy forces make a comeback?

Four elections on four continents within 10 days could profoundly reshape global politics, propelling the world further along its current authoritarian trajectory or marking a limited comeback for democratic norms.

In all four contests, basic democratic norms are at stake at a time when autocracy is advancing worldwide at an alarming rate. According to the Sweden-based V-Dem Institute, which uses multivariable assessment tools, the democratic freedoms enjoyed by the average global citizen are down to levels last seen in 1978 – long before the fall of the Berlin Wall and the collapse of communism in Europe.

Almost 1,000 arrested as police charge crowd in Paris and teargas used to stop protesters reaching other city centres

Hundreds of thousands marched in cities across France on Saturday in largely peaceful protests to support schoolchildren’s demands for more teachers and repairs to dilapidated buildings, as Emmanuel Macron faces a social and political crisis in his final months as president.

The prosecutor’s office in the southern city of Nice said on Sunday that 59 people had been taken into police custody, including 11 suspected of belonging to extreme-right groups. They were alleged to have gathered with the intent of committing violence. Some were arrested in two vehicles with masks, gloves, gas sprays and truncheons, the prosecutor’s office said in a statement to public broadcaster FranceInfo.
