"I wish England had got through, though. That was embarrassing, that was."
-- Charlie Weasley (GF5)
The English National Teams are from England (one of the four countries that together are the United Kingdom of Great Britain and Northern Ireland).
Ludo Bagman, who played for the Wimbourne Wasps, was a Beater for the English side in the 1980s (GF7, Pm, QA). Accused of passing information to a Death Eater, during the trial one of the witches on the jury congratulated him on the result of the England v Turkey match the previous weekend – instead of asking any further questions. He was acquitted (GF30).
While still at Hogwarts, one of Gilderoy Lockhart's many boastful predictions was that he would captain the English team to victory in the Quidditch World Cup before becoming the youngest ever Minister for Magic (Pm). He does know how to promote himself....
Gryffindor Quidditch team captain Oliver Wood told Harry Potter that Charlie Weasley could have played Quidditch for England if Charlie had not taken the job in Romania studying dragons (PS10). As England haven't made it to the last few Quidditch World Cups, it looks like they could have really used him on the team!
There is no mention of Quidditch or any other wizard sports in the Wikipedia entry for England (Wikipedia).
Although the date printed on the third Daily Prophet Newsletter (DP3) is 1 June 1999, the timeframe for this event is 1992-1993.
