Jessica Ennis-Hill has been selected in the Great Britain squad for August's World Athletics Championships in Beijing in her major competition appearance since giving birth. The Olympic heptathlon champion will compete in her favoured event after making herself available for selection following the London Anniversary Games.

Mo Farah, who currently faces an investigation into his relationship with coach Alberto Salazar, will defend his 5,000m and 10,000m titles in the Chinese capital. Fellow "Super Saturday" gold medallist Greg Rutherford will attempt to become the fourth Briton to complete the clean sweep of global golds in the long jump.

Liverpool's Katarina Johnson-Thompson will go in the women's event, as well as the heptathlon competition alongside Ennis-Hill ahead of their collision at the Rio 2016 Olympic Games. And though there is plenty of optimism around the European Indoor Pentathlon champion, the return of Ennis-Hill is the stand-out inclusion in a 68-strong British team.

The 29-year-old gave birth to son Reggie in July 2014 and missed the Commonwealth Games, having withdrawn from the World Championships the previous year due to an Achilles injury.

That same injury has hampered her return to competition in 2015 and had threatened her appearance in Beijing, with the Sheffield-born athlete not confirming her appearance until after running a season's best in the 100m hurdles at the Olympic Stadium on 24 July.

Elsewhere, Adam Gemini will only compete in the 4x100m relay, rather than the individual event due to injury suffered while breaking the 10-second barrier for the first time in Birmingham in June.

British Athletics performance director Neil Black said: "Beijing is a hugely important event to us, yet this is the first of three huge global competitions for us, with the Olympics in Rio next year and the home World Championships in 2017.

"In selecting athletes we were looking at either a potential to finish top eight in this year's Worlds or to give opportunities to athletes developing towards medal success in 2016 and beyond. I'm very confident we have selected a team who can be successful in Beijing, as well as use it as a platform on to further Olympic and World successes."
