Great Britain and Northern Ireland have announced their squad for next month's IAAF World Indoor Championships in Istanbul.
Distance runner Mo Farah has been included in the team, along with defending world champion Jessica Ennis.
Sprinter Dwain Chambers will look to keep hold of his 60m crown, while Perri Shakes-Drayton has recovered from a hamstring injury to take her place in the 4x400m relay team.
"This is a strong team and one that can realistically challenge for medals and make finals," said UKA head coach Charles van Commenee. "There are some good athletes coming through and I am looking forward to seeing how they perform on the senior international stage.
"There have been some good performances during the indoor season, which bodes well for Istanbul and beyond.
"The indoor season gives useful information about how athletes are progressing. It is important to remember the focus still remains on London 2012."
The event will start on March 9.
