Great Britain has been dealing exclusively in gold in Budapest this week and that run continued on Friday as the 4x200m freestyle relay team joined the party.

Eager to prove this is more than simply the Adam Peaty show, Britain retained their world title in an event the USA has traditionally dominated to make it four medals, and four golds in the swimming pool this week.

The Americans had won the previous five world titles over the longest relay prior to Britain’s back-to-back successes in Kazan and now Hungary.

And the quartet of Stephen Milne, Nicholas Grainger, Duncan Scott and James Guy produced one of the performances of the meet as they stunned Russia and the USA.

Guy was the star of the show, following up a pair of British records in the 100m butterfly with a sensational split of 1:43.80 to anchor Britain to victory, just as he had two years ago in Kazan.

And while there was some frustration that his split was more than half a second quicker than the winning time in the individual event – albeit with a rolling start – Guy was thrilled to have come through for the team.

He said: “It just shows you it is there. In the 200 free final I got giddy, got excited and went for it. It doesn't work like that anymore.

“Tonight I stuck to my game plan and it worked. That's pretty fast.

“That's the one thing I wanted to do this week was to win a gold medal. I've done it now. Especially after Rio (where he won two relay silvers)

“I'd have been upset if I'd have got slower in the 200 free, gone 1:46 and thought 'what is happening?' But it is there, I can do it. It's just putting it all together and that's it.”

Guy could add to that first medal of the week in today’s 100m butterfly final after taking nearly a second off the British record over the course of the day.

His time of 50.67 saw him into the final as the second fastest qualifier, and while new American sensation Caeleb Dressel looks untouchable, Guy looks a good bet for one of the other spots on the podium.

Although God Save the Queen has rung out four times already, there have also been some near misses in the race for medals, with Ross Murdoch the latest to miss out.

The Scot finished fourth in the 200m breaststroke – shortly after Molly Renshaw had come sixth in the women’s equivalent – but Murdoch was just thrilled to be back to somewhere near his best.

He said: “If you’d have told me in April that I would have come away with a final spot and come so close to a medal, I would have been absolutely jumping for it because I was not in a good place at the trials.”
