Tánaiste Leo Varadkar wrote to four of the world’s biggest technology companies asking them what more they could to tackle illegal gatherings and the spread of misinformation during the pandemic.

Mr Varadkar sent letters to Facebook, Twitter, Google, and TikTok in the wake of violent protests on the streets of Dublin earlier this year.
