'Remarkable achievement': Queen Elizabeth leads explosion of British joy at Raducanu's stunning Slam win

Britain's Emma Raducanu beat Canadian Leylah Fernandez 6-4 6-3 in the battle of the teens to be crowned US Open champion.

She is the first qualifier to win a Grand Slam title and the first British woman to hoist a major trophy since Virginia Wade triumphed at Wimbledon in 1977.

Here are some reactions to the win:

Britain's Queen Elizabeth, In Message To Raducanu

"Leylah Fernandez will be back -both are champions but Emma has the trophy- well done!!!"

12-time Grand Slam Singles Winner Billie Jean King 

"What a terrific display of competition & maturity from two exceptional players. It is wonderful to see this generation living our dream. I can't remember a #USOpen with better crowd support. Thank you, NY, the greatest fans in the world.

"And congratulations, Emma!"

"Well done Emma Raducanu, the first of many duels with Leylah Fernandez. I've no doubt many more majors await for both of you. Another historic moment at the #USOpen - congratulations."

7-time Grand Slam Winner Mats Wilander on Eurosport 

"I have never heard a crowd in Grand Slam tennis being this loud, this appreciative of the players and the player responding. This was an epic of the US Open. It was a great comeback of the U.S. Open, it was just an amazing two weeks."

Alex Corretja, Former World No. 2 and Eurosport Tennis Expert

"I don't think we will see this again from a player from qualifiers, not losing games, sets, that's something superior Emma did very well. It's such great news for tennis, women's tennis and sports in general."

British Actor Stephen Fry

"What a glorious day for two remarkable young women. Yes, it may be 'only' sport, but in that 'only' there can be found so much of human joy, despair, glory, disappointment, wonder and hope. A brief flicker of light in a dark world. #EmmaRaducanu #LeylahFernandez #USOpenFinal"
