The Olympic gymnast Louis Smith has received his Member of the British Empire (MBE) medal in an investiture ceremony at Buckingham Palace.
Olympic medallist-turned-Strictly Come Dancing champion Louis Smith described his MBE as "without a doubt the proudest moment of my life".
The Peterborough gymnast was a member of Britain's surprise bronze medal success in the men's team competition at the London 2012 Olympics.
He also won silver on the pommel horse with one of the hardest routines in the world.
"To receive this honour is out of this world and something I never would have dreamt of as I grew up in the sport of gymnastics," said Smith, 23.
Olympic gymnast Louis Smith has been crowned the winner of Strictly Come Dancing.
The 23-year-old silver medallist, who has wowed judges with his polished backflips and somersaults, beat Kimberley Walsh, Denise van Outen and Dani Harmer to the ballroom dancing competition's glitterball trophy.
Together with professional dance partner Flavia Cacace, Smith danced the ‘Dr. Wanna Do’ Charleston, Take That’s ‘Rule The World’ and a Dirty Dancing-themed salsa - which he performed shirtless - in tonight's final.
Oympic medal-winning gymnast Louis Smith stormed to the top of the Strictly Come Dancing leaderboard tonight as an evening of spooky routines dominated the dancefloor.
He received a top score of 35 points during the Halloween-themed show as judge Bruno Tonioli described his routine as "the first killer tango of the season".
Smith and partner Flavia Cacace played a pair of zombies dancing to Rihanna's hit Disturbia.
Darcey Bussell said the Olympic star was "spookily good" and performed "the best tango of the night", while Len Goodman said he wanted to turn the clocks back early to watch the gymnast dance again.
