Dual Gold Cup winner Kauto Star has been put down after a serious injury sustained whilst in his paddock.
Speaking on At The Races, his former trainer Paul Nicholls called it an "extremely sad day". Nicholls described the horse as a "champion of all champions" that was so good for National Hunt racing.
In a career record that included 23 wins from 41 starts, Kauto Star won the King George VI Chase five times and Nicholls said he "used to light up Kempton Park [at Christmas]."
Career highlights:
2 x Cheltenham Gold Cup wins (2007, 2009)
5 x Kempton Park King George VI wins (2006, 2007, 2008, 2009, 2011)
2 x Sandown Park Tingle Creek wins (2005, 2006)
