Having safely secured his third grand prix win of the season for Mercedes in Bahrain on Sunday, the big cheese of Formula One will be big brother for a while. Lewis Hamilton’s younger sibling Nicolas, who suffers from cerebral palsy, is preparing to become the first disabled competitor to compete in the British Touring Car Championship, for Audi, starting in June.

Lewis, whose next race is the Spanish Grand Prix on May 10, admits Nicolas shares the family stubborn streak which does not always welcome advice but recently he has been able to adopt a mentor’s role. He said: ‘We Hamiltons are generally very stubborn. We want to do it on our own. We think we can do it without guidance. When my brother was really young, I was always guiding but then he got to an age when he was doing his own thing. But now we’ve got to a stage where my brother is asking me for advice. It’s the greatest feeling to be able to help. ‘I’ve been through the racing world, so hopefully I’ve found a good solution that could help him shape his own solution. I’m really proud of that.’ Asked if his brother was strong, Hamilton said: ‘He’s got very big fists. If he caught you with a punch, you’d know about it. I always make sure that I show him “I’m your older brother”.’ Hamilton crosses the line in Bahrain ahead of Kimi Raikkonen to claim his third win from four races this term .
