‘Has Trump learned his lesson?’ Sadiq Khan urges big tech to stop hate speech

London mayor, a frequent target for Trump, says level of racial abuse on social media required him to receive police protection

From a stage in the heart of Silicon Valley, London mayor Sadiq Khan called on tech companies to rein in hate speech, speaking about his own experience of abuse amplified by one of the most powerful figures on social media.

He was referencing Donald Trump, who frequently used the mayor as an online punching bag, calling Khan a stone-cold loser" and very dumb". Khan, whose family are from Pakistan, said the amount of racial abuse he received on social media increased by 2,000% under Trump and required him to receive police protection.
