Olympics have always been 'an obsession' - swimmer Daniel Jervis

Daniel Jervis says a first Olympic Games appearance would be "everything to him" after his victory at swimming's Tokyo trials in London.

The 24-year-old from south Wales won the men's 1500m freestyle in 14:51.49 - more than four seconds inside the Olympic consideration time.

Jervis' selection for the delayed Tokyo 2020 Games could be confirmed next week.
