Kane stopped the clock in the heats at 1min 11.92sec to comfortably finish below the required time of 1:13.24.

The youngster, who has Stargardt disease, which affects her vision, set a British record in the process and is now in line to compete at Rio 2016.

“It was a bit scary being out there against the really good swimmers, but they pushed me and it helped,” Kane said.

“I definitely did not think about the Paralympics this year.

“In the back of my head I was hoping I might be in with a chance of Tokyo in four years’ time, but the possibility of Rio is just amazing.”

Kane will be 13 by the time this year’s Paralympic Games are due to get underway on September 7 and will miss out on becoming Britain’s youngest-ever competitor should she be selected.

That honour remains with England's Joanne Round, another swimmer, who was was just 12 when she competed at Seoul in 1988. 

“She’s worked extremely hard, has a great attitude in training and it’s paid off,” Kane's coach Sharon McIntyre said.

“We’ve been doing a lot of endurance based work, no real taper because of her age, she’s put in the work and here we are.

“We’ve also not allowed ourselves to get carried away with any talk of Rio.

“We speak before the race about her being relaxed and swimming fast and I will be asking her to do the same for the rest of the week in her other events.”

Other athletes to achieve qualifying times at the British Para-Swimming International Meet included London 2012 S8 200m medley champion Ollie Hynd and fellow Paralympic gold medallist Jonathan Fox, who competes in the S7 category.

A notable absentee from the competition was Erraid Davies, ruled out after she was declared ineligible following reclassification.

Medical experts in Glasgow claimed she was not disabled enough to compete in Paralympic events.
