Defending Wimbledon champion Novak Djokovic has been confirmed as the top seed in this year's men's singles at the All England Club, while French Open winner Maria Sharapova is the top seed in the womens' singles.
Serbia's Djokovic, the current world number one, was beaten by Rafael Nadal in the French Open final earlier this month, but he retains the top seeding ahead of the second seeded Spaniard.
Djokovic's defeat to Nadal in Paris marked the end of a run of three successive grand slam final victories over the world number two, which started when he won Wimbledon for the first time last year.
Federer at three
Six-time Wimbledon champion Roger Federer is seeded third as he seeks to win a grand slam for the first time since the 2010 Australian Open.
Britain's Andy Murray, a loser in the Wimbledon semi-finals for the last three years, is the fourth seed, while France's Jo-Wilfried Tsonga, a beaten semi-finalist at Wimbledon last year, is seeded fifth.
Maria at the top
In the women's singles, the seedings reflect the current WTA Tour rankings, with world number one Sharapova selected to be the top seed ahead of reigning champion Petra Kvitova. Sharapova's victory at the French Open at the Roland Garros gave her a career grand slam.
Five-time champion Venus Williams and Kim Clijsters are unseeded for the first time in more than a decade.
Williams, who played in eight Wimbledon finals from 2000-09, is unseeded for the first time since her debut in 1997. She has dropped to 55th in the ranking. Clijsters is ranked 53rd.
