BERN: Switzerland is sending 109 athletes to the Rio de Janeiro Olympics with the aim of winning at least five medals.

Team leader Ralph Stoeckli says the Swiss can win more if their medal candidates stay healthy and deliver their best performances.

It's the biggest Swiss Olympic team since 114 athletes competed at the 1996 Atlanta Olympics.

The lineup includes Roger Federer at his fifth Summer Games. He won gold in doubles with Stan Wawrinka at the 2008 Beijing Olympics, and will renew the partnership in Rio.

Federer's silver in men's singles was among four Swiss medals at the 2012 London Olympics.

Both gold medalists from four years ago will defend their titles in Rio: Nicola Spirig in triathlon, and Steve Guerdat in equestrian jumping.
