Tom Daley will return to synchronised action for the British diving team in July's World Championships in Shanghai.
The 17-year-old missed the 10m synchro event at the National Championships in June following his father Rob's death from cancer on 27 May.
Daley will be joined by dive partner Pete Waterfield, with both men also competing in the platform events.
A team of 11 will travel to Shanghai looking to qualify for the 2012 Olympics in London.
Daley, who became Britain's youngest competitor at the 2008 Olympics in Beijing, will defend the individual platform title he won at the 2009 World Championships in Rome.
He also won two gold medals for England at the 2010 Commonwealth Games, but was forced to settle for second place behind Waterfield on his return to the 10m platform competition at the 2011 National Championships.
Daley's father Rob, was diagnosed with a brain tumour in 2006 and consequently had 80% of a fist-sized tumour removed.
He had been in remission until a routine health check in 2010 discovered a tumour had returned.
Daley's father had been a huge support, and even gave up his electrician's business to follow his son to events around the world, and watched the then 15-year-old Tom become Britain's first individual diving world champion.
Daley and Waterfield will face a tough challenge from world number one diving nation, China, in the 10m synchro event in Shanghai, but recently beat the Chinese pair at the Diving World Series in Sheffield.
British 3m Springboard Champion Jack Laugher will compete in his first World Championships in Shanghai. But after winning double gold at the Junior Championships in 2010, the 16-year old is ready for the challenge.
"It is such a great feeling to know that I will be competing in such a high calibre event. I have worked really hard to get on to the team and this year," Laugher said.
"I want to learn as much as I can before next year so this trip is going to be about gaining knowledge and experience of competing against the best in the world.
"I think it is going to be really invaluable to get such a big event under my belt before next year too."
Other debutantes in the British team include Jenny Cowen, Alicia Blagg and Hannah Starling.
