“I’m incredibly proud of my brother, he’s still a great voice,” Lewis Hamilton said when asked about his travels ahead of this weekend’s Azerbaijan Grand Prix. “Every year he raises his own money (to play).

“He’s obviously played in a series of games and a sport that doesn’t have a lot of opportunities … especially with disabilities. He’s represented so much.

“It’s been difficult – he’s been trying to make up for what’s missing in his leg and it’s been a constant battle.

“But he finished sixth in the race and I was just standing in the crowd, just watching as a fan. I was so excited!

“Nobody knew I was actually there, I was just jumping up and down trying to support him. Very proud and excited this weekend.

“The weather was great! He pitted on the first lap, so everyone else was on slicks and he made up for it.”

Nicholas Hamilton finished 21st twice in the other two BTCC races at Donington, his third full-time start in the series in a row.
