Royal Mail has announced a significant change it is making to all letters the public will receive this week in a bid to celebrate Emma Raducanu's success.
Emma Raducanu became the first British female tennis player to win a Grand Slam since 1977 when she defeated Leylah Fernandez in the U.S Open Final on Saturday.
The 18-year-old defeated Fernandez 6-4 6-3 in the final. She didn't even drop a set on her way to claiming the title.

To commemorate her amazing achievement the Royal Mail will issue a special postmark congratulating her on her success.

It reads: " Congratulations Emma Raducanu, 2021 US Open Women’s Champion, A First Class performance!"
The congratulatory postmark will be on stamped mail from 13-16 September.
After winning the trophy Emma said: "It means everything to hold this trophy and I don't want to let go right now!
"I've always dreamed of winning a Grand Slam. You just say these things. But to have the belief I did, and actually winning, I can't believe it.
"For me, I don't feel absolutely any pressure. I'm still only 18 and I'm just having a free swing at anything that comes my way.
Emma even had a flight booked back to the UK 17 days ago in case she didn't make it through qualifying.
