Andy Murray is Britain's only seeded player for the Olympic tennis tournament at Wimbledon, which begins on Saturday.
In the absence of the injured Rafael Nadal, the gold medallist in Beijing four years ago, Wimbledon finalist Murray is seeded third for the men's singles behind world number one Roger Federer of Switzerland and Serbia's Novak Djokovic.
David Ferrer, the leading Spaniard in Nadal's absence, is fourth with France's Jo-Wilfried Tsonga fifth, while Czech Tomas Berdych, Serb Janko Tipsarevic and Argentina's Juan Martin Del Potro make up the top eight.
Unlike at the grand slams, where there are 32 seeds in a 128-strong field, the Olympic singles tournament is a 64-man field featuring 16 seeds.
World number one Victoria Azarenka of Belarus heads the seedings for the women's singles with Poland's Agnieszka Radwanska second followed by Russian Maria Sharapova and Wimbledon champion Serena Williams of the USA.
The men's doubles field is headed by American twins Bob and Mike Bryan, with defending champions Federer and Stanislas Wawrinka seeded sixth.
Liezel Huber and Lisa Raymond of the US top the standings in the women's doubles but their countrywomen Venus and Serena Williams, the Beijing gold medallists and Wimbledon champions, are unseeded.
The draw for the singles and doubles takes place on Thursday morning at 11am, while the entries for the mixed doubles will be decided over the weekend with the draw taking place on Tuesday.
