Ginger McCain, trainer of the legendary Grand National winner Red Rum, has died aged 80 after suffering from cancer.
McCain guided "Rummy" to three victories and two second places in a five-year period during the 1970s.
He was nicknamed 'Mister Aintree' for his record at the Merseyside track and won a fourth National with Amberleigh House in 2004.
In 2006, McCain handed the reins to son Donald who won the Grand National with Ballabriggs this year.
Ginger McCain had been an unknown taxi driver and car salesman who trained a few racehorses at Southport before Red Rum achieved his never-to-be-repeated record in the 1970s.
"When injury forced the horse's retirement in 1978 McCain and his wife Beryl organised dozens of public appearances before Red Rum died in 1995.
"Just as Rummy became a household name, so did his trainer with his infectious laugh and colourful politically-incorrect turn of phrase.
"A long, less successful period post Red Rum, was ended by Amberleigh House who gave McCain a quite unforgettable fourth Grand National win in 2004
McCain's wife Beryl said: "Donald - Ginger as we all knew him - passed away peacefully in his sleep after a short illness this morning - he would have been 81 on Wednesday.
"There will be a private family funeral followed by a later memorial service, for which there will be more information in the coming weeks.
"Joanne, Donald Jnr and I appreciate all the kindness we are being shown and, at this difficult time, would appreciate it if we were afforded some privacy."
Jockey Tony McCoy, who ended a long wait for a Grand National victory in 2010 on Don't Push It, wrote on Twitter: "Sad to hear about the death of Aintree legend Ginger McCain, trainer of the great Red Rum. My thoughts are with his family R.I.P."
Former jockey Mick Fitzgerald, who was successful in the 1996 race on Rough Quest, told Sky Sports News: "It's a very sad to hear the news. He leaves a legacy. Everytime you think of the Grand National, you think of Ginger. He was the National, to be honest.
"If you ever wanted a colourful quote you spoke to Ginger. He was never afraid to speak his mind. He believed in what he was doing and believed in the Grand National and racing needs characters like him."
BBC horse racing presenter Clare Balding wrote on Twitter : "Ginger McCain was 3 days short of his 81st birthday. He was an old-fashioned type & said what he thought but he was a character all right.
"Very sad for Beryl, Donald & the rest of the McCain family.
"Whenever I approached Ginger with a microphone it raised the heart rate. He might swear, say something offensive or be pertinent & funny."
Former racing commentator Sir Peter O'Sullevan spoke of McCain's brilliant handling of Red Rum, who was prone to lameness.
"Red Rum had very delicate, tender feet and had been with several skilful trainers before Ginger bought him," he said.
"Of course, he trained on the sands at Southport. I don't think we'd ever have heard of Red Rum if he'd gone anywhere else."
