Unions have called for more demonstrations to coincide with the King and Queen Consort's visit to Paris, due to take place on Sunday.

A banquet at the Palace of Versailles hosted by Mr Macron could be moved or even cancelled, according to local reports.

It is understood the trip's logistics have been under review for some days, amid massive protests in the French capital.

Security concerns could mean the royals' contact with the public is reduced.

After France, the couple are scheduled to visit Berlin from 29-31 March.

The unions' announcement of weekend protests follows a record turnout in Paris against the unpopular bill to increase the retirement age from 62 to 64.

French authorities say 119,000 people marched on Thursday, believed to be the biggest demonstration in the capital in the current wave of protests.

The vast majority were peaceful but police used tear gas to disperse rioters who threw objects and fireworks.

Across France, more than one million people are said to have joined marches on Thursday - a day after Mr Macron forced through the law without a vote.

Protests in cities such as Lyon, Nantes, and Rennes also saw outbreaks of violence.

In Lorient, in western France, the courtyard of a police station was set alight and its windows smashed, while an administrative building was also attacked.

Strikes linked to the pension changes have also disrupted travel across the country, with demonstrations blocking train stations, Charles de Gaulle Airport in Paris and ports.
