Wigan's Hayley Jones was part of Great Britain's women's 4x100 metres relay squad who were promoted to bronze after the French team were disqualified at the World Championships in Moscow tonight.
Britain came home in fourth place but were upgraded following a successful protest against the France team, who were second.
The International Association of Athletics Federations confirmed the French had been disqualified because their second baton exchange took place outside the changeover zone.
The French took their case to the jury of appeal, but it was rejected.
The news of the promotion came barely two hours after Britain's men's 4x100m team were stripped of their bronze after being disqualified over an identical issue.
It meant Britain finished the championships with six medals in total.
