Bethany Firth finished off the British championships by completing a full set of gold medals and a new world record.
2012 Paralympic gold medalist Firth, who recently swapped her allegiance from Ireland to Great Britain, was in stunning form over the four days, winning gold every time she entered the pool.
Ards swimmer Firth had bagged gold in the 100m breaststroke, 200m individual medley, 100m backstroke and yesterday 200m free gold with a new world record of 2:05.93.
Firth's nearest rival in the 200m free was London 2012 gold medalist Jessica Jane Applegate – and she was five seconds behind the 18-year-old, whose long term sights will be on Rio.
It was Firth's second world record of the championships as she also set a new global best of 1:06.00 for the 100m backstroke.
She also happened to clock the fastest ever S14 200m IM time with 2:24.89 but that is a new event in this category and a world record cannot be ratified until after 12 months.
Ards coach Nelson Lindsay said: "Bethany just gets better and better and she's only been swimming five years. These were four tremendous performances and the British coaches were very pleased with what they saw."
