The PGA's longest running event is one of the hardest to win - players are only eligible to compete in the championship during their three years of training.
Competition is not surprisingly fierce and equally unsurprising is the fact some of golf's biggest names have made their mark on the tournament down the years.
Previous winners include Dai Rees (1935 and 1936), Peter Alliss (1952), David Thomas (1955), Neil Coles (1956), Tony Jacklin (1965) and Barry Lane (1983).
Matthew Tottey etched his name into the history books at The London Club by achieving the rare feat of winning a second Assistants' title (2003 and 2005). Dai Rees and Harry Weetman (1949 and '50) were the only other two time champions until Matthew Cort secured a hat-trick of titles in 2011, 2012 and 2013.
