Lewis Hamilton paid a celebratory visit to the troops yesterday at Mercedes' headquarters at Brackley and Brixworth

The 2017 world champion was offered a guard of honor upon his arrival but later paid a warm tribute of his own to all those, up and down the ranks, who made their contribution to his fourth world title.

"This a very emotional day. I was not expecting this," Hamilton said.

"Today is something that I will never forget, turning up at the front gate of the factory and seeing everyone out on the street to welcome me - I'm blown away. This has been an incredible year, it's been an incredible journey together.

"There's a huge amount of respect and appreciation I have for everyone. Thank you all for helping me achieve my dreams, it would not have been possible without you."
