Three-time Formula 1 world champion Niki Lauda has died aged 70. The Austrian had been battling health issues since mid-last year, including a lung transplant in August that required a two-month stay in hospital. He was then hospitalised again for a short period at the beginning of 2019 after contracting a flu infection. There have been reports from Austrian press in the recent days that he had been receiving kidney dialysis in Switzerland. It has now been confirmed that he has succumbed to his ill health, passing away on Monday surrounded by family.
