Formula One world champion Lewis Hamilton said he was speechless after being made an honorary citizen of Brazil when the lower house of parliament passed a bill on Thursday. The move had been proposed by congressman Andre Figueiredo after last year's Brazilian Grand Prix was won by the British driver who unfurled the Brazilian flag at Sao Paulo's Interlagos circuit. Hamilton backed the move in April, when he visited Sao Paulo to deliver a keynote speech at an event focused on business and digital transformation, saying he would be honoured. "Today I was granted honorary citizenship to one of my favourite places in the world," Hamilton, who is racing in Azerbaijan this weekend, told his 28.4 million followers on Instagram.
