The 12-time Paralympic champion stormed to another world title with a time of 1min 9.79sec to finish clear of Britain's Stephanie Slater and Ukrainian Kateryna Istomina and add more precious metal to her growing collection.

New Zealand's Mary Fisher was another of a handful of athletes to set a world best time as she stormed to a fourth title in the women's 100m butterfly S11.

The 20-year-old was in formidable form once again as she added to the treble of gold medals she had already achieved this week with another gold, clocking a world record time of 1:16.08 to finish ahead of Ukraine's Olga Iakibuk and Swede Maja Reichard in second and third respectively.

Her compatriot Sophie Pascoe was not to be outdone on the night as she not only set a world record in her women's 100m butterfly S10 heat, but went on to break that record just hours later in her final, where she took gold with a time of 1:03.95.

Poland's Olivia Jablowska finished in the silver medal position in a European record time of 1:08.54, ahead of France's Elodie Lorandi in bronze.

New Zealand's Sophie Pascoe set a world record twice in the same day as she won gold in the women's 100m butterfly S10

The winner of five gold medals at London 2012, Ihar Boki from Belarus, set the world record for the men's 400m freestyle S13 at last summer's Games, but he bettered his previous best time by over three seconds in Montreal to set a world record time of 3:55.56 en route to gold, holding off the challenge of silver medallist Iaroslav Denysenko of Ukraine and bronze medallist Charles Bouwer from South Africa.

Australian Paralympic champion Brendan Hall retained his 400m freestyle S9 world title in style as he defeated his own world record to take gold in a time of 4:09.93, ahead of Italy's Federico Morlacchi and Spain's Mari Alcaraz in silver and bronze respectively.

After raking in four gold medals yesterday, there was more glory for Great Britain on day five as 16-year-old Josef Craig won his second gold medal of the Championships in the men's 100m freestyle S7 with a time of 1:01.74.

The Briton held off the challenge of Australia's Paralympic silver medallist Matthew Levy, who settled for silver just ahead of Yevhenoy Bohodayko of Ukraine in third.

"I'm really happy for it obviously but it was my second event coming into this competition," said the Paralympic and now double world champion.

"I'm not really a sprinter, I'm more of a long-distancer and it usually takes me a while for me to get into the race.

"But I've been working with Mick Massey, Nic Rowley and my home coach Paul Robinson and I've managed to get better at all three of my events which I'm thankful for.

"Matthew [Levy] was off like a bullet in that second 50m.

"I don't know how he did it and I don't know how I pulled it back either because with 25m to go, my legs felt like they'd fallen off and my arms were dead already.

"I don't know what happened but I've been practising my finish vigorously and it must have seen me through."

The Ukrainians extended their lead at the top of the medal table once again under pressure from Britain as Olga Sviderska made it four gold medals from four with a world record time of 1:37.58 in the women's 100m freestyle S3, as her compatriot Dmytro Vynohradets earned a golden quadruple of his own in the men's equivalent.

Another Ukrainian, Danylo Chufarov, notched up a second world title with victory in the 400m freestyle S12 in a world record time of 4:05.95, beating the holder of the previous world record, Sergey Punko, who had to settle for silver, whilst Britain's James Clegg took bronze.

Ukraine locked out the podium in the women's 100m freestyle S2 as Ganna Ielisavetska led the way with a world record time of 2:16.95, whilst her team-mates Iryna Sotska and Darya Kopayeva followed her to take silver and bronze respectively.
