Wilson has been touted as a favourite to win an Olympic gold after topping the qualifying stages with a score of 143 out of 150.

The 25-year-old farmer’s son from Dorset is the world record holder and world number two in the event. His chances looked good after neither world number one Josh Richmond or reigning Olympic champion Walton Eller, both of the USA, made the London 2012 final.

Instead, Wilson was up against Russians Vasily Mosin and Vitaly Fokeev, Feehaid Aldeehani of Kuwait, Sweden’s Hakan Dahlby and Hungarian Richard Bognar.

Peter Wilson’s Team GB gold medal is Britain’s first in shooting since Richard Faulds’ victory in Sydney 12 years ago.
