British Prime Minister Theresa May and French President Emmanuel Macron want to get tech giants such as Facebook and Google to do more to remove extremist material from the internet.

On her first trip abroad since losing her majority in parliament, May suggested social media firms could be fined if they fail to take swift action.

“We’re launching a joint UK-French campaign to ensure that the internet cannot be used as a safe space for terrorists and criminals, and that it cannot be used to host the radicalising material that leads to so much harm,” May told reporters in Paris on Tuesday (June 13), speaking alongside Macron.

“Our discussions today have focused on the greatest security challenge our two countries face: tackling terrorism and rooting out the extremism that fuels it. Both our countries have sadly experienced the horrors of terrorism all too recently,” May said.

Social media firms such as Twitter say they are already investing heavily to take down hate speech and violent content from their platforms, but that they struggle to identify replacement accounts that quickly reappear.

Tribute at the Stade de France

May and Macron met for a working dinner before attending a friendly football match between France and England.

At the Stade de France, supporters paid tribute to the victims of the recent Islamist militant attacks in Manchester and London.

The Oasis song “Don’t Look Back in Anger” rang out as fans held up red and white placards to form the England flag. “La Marseillaise” was then played before “God Save the Queen”, with the words of both displayed on giant screens to help fans sing along.

Both teams then formed a circle at the centre of the pitch and a minute’s silence was observed before the game started. ( Natalle Huet - Euronews)
