Thousands took to the streets across France to oppose some of Mr Macron’s policies, such as raising the retirement age from 65 to 62, and also to demand higher wages. Most of the marches were peaceful, but violence erupted in the capital as police used tear gas and clashed with black-clad anarchists. Police arrested 54 people, including a woman who attacked a firefighter trying to put out a fire, Interior Minister Gerald Darmanin said on Twitter. He added that eight police officers were injured.

The “Black Bloc” anarchists attacked a McDonald’s in Place Leon Blum and damaged several real estate agencies, breaking their windows and setting fire to buckets. Police responded with tear gas. About 250 rallies were organized in Paris and other cities, such as Lille, Nantes, Toulouse and Marseille. A total of 116,500 people protested across the country, including 24,000 in the capital.

He also accused the president of “inaction” on environmental issues.

He said he still hoped an agreement could be reached on building a new union of the left by Sunday night. Additional Reuters report
