Dwain Chambers came flying down the home straight to earn Great Britain, at first glance, the bronze.

The quartet of Adam Gemili, Harry Aikines-Aryeetey, James Ellington and Chambers clocked a season’s best 37.80secs, the veteran anchor-leg runner chasing down Germany to claim third.

However, the second changeover from Aikines-Aryeetey to Ellington looked like it might have taken place out of the box, putting the result in doubt.

It was then confirmed by the British team's management that the team were stripped of their bronze medal because of the faulty changeover.

The second changeover from Harry Aikines-Aryeetey to James Ellington took place out of the designated box, meaning the result was always likely to be reversed.

Dwain Chambers came flying down the home straight to bring the team home in third place, but after doing a lap of honour they were given the bad news.

As a result, Canada were promoted to bronze.

It is the latest in a long line of relay failures for Britain’s sprinters. It is the sixth major championship out of seven in which they have failed to get the baton round properly.

UK Athletics performance director and acting head coach Neil Black told the BBC: "It's pretty gutting and I'm sure we all feel the same but that's the sport.''

The man Black is filling in for as head coach is Peter Eriksson, who left his position at UKA in late June, to take up the same role with Canada.

The British quartet clocked a season’s best 37.80 seconds, but it proved irrelevant.

If British relay blunders have become expected, so too have Jamaican wins.

Usain Bolt performed a Cossack dance on the track for the Luzhniki Stadium crowd, which looked at his fullest it has been all championships, after the race.

Addressing the crowd, he said: “I am very satisfied. It’s a wonderful energy that’s coming out.”

Bolt has now won 10 World Championship medals, eight gold and two silver, to equal Carl Lewis’ men’s record.
