In 2013, which drinks manufacturer replaced John Smith's as sponsor of the British Grand National horse race?

The Grand National is a National Hunt horse race held annually at Aintree Racecourse, near Liverpool, England. First run in 1839, it is a handicap steeplechase over an official distance of about 4 miles and 2½ furlongs (4 miles 514 yards (6.907 km)), with horses jumping 30 fences over two laps. It is the most valuable jump race in Europe, with a prize fund of £1 million in 2017. An event that is prominent in British culture, the race is popular amongst many people who do not normally watch or bet on horse racing at other times of the year.

The Grand National was founded by William Lynn, a syndicate head and proprietor of the Waterloo Hotel, on land he leased in Aintree from William Molyneux, 2nd Earl of Sefton. Lynn set out a course, built a grandstand, and Lord Sefton laid the foundation stone on 7 February 1829.The first running was in 1836 and was won by The Duke.

In August 2013 Crabbie's was announced as the new sponsor of the Grand National. The three-year deal between the alcoholic ginger beer producer and Aintree saw the race run for a record purse of £1 million in 2014.

In March 2016 it was announced that Randox Health would take over from Crabbie's as official partners of the Grand National festival from 2017, for at least five years. The sponsorship is controversial as Aintree's chairwoman, Rose Paterson, is married to Owen Paterson, a Member of Parliament who also earns a £50,000 annual fee as a consultant for Randox.
