Queen Elizabeth II on Monday congratulated the England cricket team on their Ashes victory over Australia, praising both sides for the performances in the five-Test series, a spokesman said.
Meanwhile British Prime Minister Gordon Brown wrote to England captain Andrew Strauss, praising his "patience, resolution and courage" and saying the series had "gripped the entire nation".
Queen Elizabeth, 83, is head of state of both Britain and Australia.
"The queen congratulates the England team on their victory in the Ashes, and extends her good wishes to both teams on their excellent performances over the course of the series," said a Buckingham Palace spokesman.
England regained the Ashes with a 2-1 win, repeating their 2005 series victory on home soil with a 197-run win in the final Test at The Oval in south London on Sunday.
The side celebrated in a much more muted fashion than four years ago, when players drank though the night and some could barely keep their eyes open during the celebrations the day after winning the famous urn.
Brown invited the England squad to a party to be held at his Downing Street office.
In keeping with the toned down theme, it is likely to be a far more civilised affair than the reception Brown's predecessor Tony Blair held back in 2005.
The notorious reception allegedy saw booze-fuelled players urinating in the garden and getting the prime minister to fetch more beers amid the joyous celebrations.
"I wanted to write to congratulate you and the entire England squad on regaining the Ashes," Brown said in his letter to Strauss.
"The series has been yet another wonderful showcase for cricket and for all that is great about sport.
"It has provided high sporting drama throughout the summer that has yet again gripped the entire nation, and to win the Ashes with your magnificent display at The Oval -- and coming back from the defeat at Headingley in the Fourth Test -- shows great determination and commitment.
"There have been many outstanding performances this summer on both sides, but throughout the series you have led England from the front, with patience, resolution and courage. The country is extremely proud of what you have achieved this summer.
"I would like to invite the England squad to Downing Street for a reception to celebrate your victory. We will be in touch to arrange this very shortly."
