Steph's on her way to Rio
It will be the 25-year-old’s debut at the Paralympics.
Slater, a seven-time European champion, said: “I’m really honoured to be selected to represent GB at my first Paralympic Games.
“It’s been a tough year, having to spend time out of the water due to injury and ill health.
“So after all that, it has been a massive relief to have met the qualifying times and to achieve my goal.
“Having missed London 2012, it’s fantastic to discover that I can still represent my country at an elite level.
“I’m going to wear the GB tracksuit in Rio with pride.”
