Team GB will finish second in the Rio Olympics medal table, coming above China who traditionally do well in the Olympic Games.
China is one of the most dominant nations at the Games as they have won more than 200 gold medals since returning to compete in 1984.
Britain currently holds 27 golds while China has 26 in Rio - meaning that China cannot possibly pass Britain and regain second place.
With at least 67 medals altogether, Britain has increased its medal tally at the Olympics immediately following the one it hosted - something no country has done since the modern Olympic era began in 1896.
It also means the team has smashed the target of 48 medals, set by UK sport, and making the Rio Olympics the most successful Olympic Games for Britain in over a century.
