And the world record is gone into the bargain! Not just broken either shattered into a thousand tiny pieces.

3:30.98 is the new mark, replacing the 3:31.72 set by Netherlands in 2009.

The final medal event of the evening is the women's 4x100m freestyle relay and Australia are the team to beat with an all-star squad featuring Emma McKeon and Cate Campbell.

Scotland's Michael Jamieson after winning silver in the men's 200m breaststroke: "Ross took a big chunk out of his personal best and so deserved to win. I don't prepare to come second though and it is just not good enough."

"That is world class from Ross Murdoch, he's only just missed out on the world record. Michael Jamieson has been beaten tonight by one of the best breaststroke swimmers in the world so he can have no complaints."

Ross Murdoch speaking to BBC One after victory in the men's 200m breaststroke: "There is no way that just happened. In the last 100m the sound was just amazing and it drove me on. I felt really good this morning in the heats but I didn't believe that I could do that. It is my grandad's 70th birthday so that is for him."

Karen Pickering
BBC Sport aquatic sports expert & ex-CWG champion

"Ross Murdoch cannot believe it with the widest eyes I've ever seen and shaking his head in utter disbelief. He's not just beaten Michael Jamieson, he's taken his British record as well. Ross just went past Michael like he was a club swimmer."

What a swim and what a reaction to match it!

Ross Murdoch stares at the result on the digital display above the pool with his mouth gaping agog.

He has scalped the poster boy of the Games with an extraordinary swim and a new British and Commonwealth Games record.

Andrew Willis takes bronze for England.

Away in the final of the men's 200m breaststroke and at half way it is Christian Sprenger leading from Michael Jamieson and Ross Murdoch.

And Murdoch leads at 150m...

Australian rival Christian Sprenger took silver behind Michael Jamieson in Delhi four years ago, is the second fastest man in the Commonwealth this year and a former world record holder.

Jamieson's compatriot Ross Murdoch is also in red-hot form.

Let's find out what it all means...

While the men sort out the 100m backstroke final line-up, we are just a matter of minutes from Michael Jamieson's big night out in the 200m breaststroke final.

The 25-year-old swam at Tollcross as a youngster and won silver in his pet event at London 2012.

He faces some significant opposition though who will want to deny him a happy homecoming.

"England's Commonwealth champion Ashley McKenzie was waiting to see his room mate, Colin Oates, collect his gold medal so I thought I'd pester him.

"'I've got the World Championships in a couple of weeks so this is obviously a good stepping stone'," he says.

"'Coming here and getting gold is amazing and with my room mate getting gold as well makes it extra special'."

On Scotland's Michael Jamieson in the 200m breaststroke final tonight: ""It's a massive risk-reward opportunity, if he does it he will absolutely be the man of the Games - if he doesn't, he's got to deal with all that pressure.

"I think he recognises that opportunity but it is a stacked event, there are couple of youngsters, you've got the Aussies who are looking really good and I don't know how you deal with that pressure. We passed four posters this morning on the road of Michael looking fantastic so everyone knows and they are hot tickets tonight for this 200m breaststroke final."

The line-up for 100m butterfly final is being shaken out across two semi-finals at the Tollcross Swimming Centre.

Canadian Katerine Savard takes the first of the two races ahead of Australia's Emma McKeon and Jemma Lowe of Wales in third.

In the second race England's Siobhan Marie O'Connor, fresh from winning 200m freestyle silver, romps home ahead of Alicia Coutts of Australia and Elen Gandy, who used to represent England and Great Britain, but defected to join up with Australia after London 2012.

Gandy was born in Bromley, London, but emigrated with her family to Australia at the age of 16.

Scotland's Alan Clyne has been taken to the limits in his round of 32 singles match against India's Harinder Pal Sandhu.

After an hour and 33 minutes he has prevailed 12-14 11-9 13-15 11-1 11-9 to advance to the next round.

Gold in the women's under-57kgs went to England's Nekoda Davis, who beat Scot Stephanie Inglis in the final.

Davis, based at British Judo's Centre of Excellence in Walsall, scored a Waza-ari throw, which she followed up with a 25-seconds hold-down to clinch the title.

There was, though, more home success for Scotland as Glasgow fighter Connie Ramsay, a defeated quarter-finalist earlier on Thursday, secured bronze when she pinned down Cameroon fighter Paule Sitcheping.

England's Colin Oates, gold medallist in the -66kg, beat close friend James Millar of Scotland in the semi-finals.

"I would have liked for that fight to have been in the final, and am really pleased he took a bronze medal, because he has worked so hard for so many years and missed out for a lot of events, then got a late call-up for this.

"But I had one goal - it was a gold medal, that is what I came here to deliver."
