Adam Peaty’s dominant European Championships continued by adding another gold medal to his collection in the 4x100m medley mixed relay with teammates James Guy, Georgia Davies and Freya Anderson.
The British quartet smashed the European record on the way to victory with Freya Anderson speeding down the final leg to finish in a spectacular 3m 40.18s.
Earlier two-time Commonwealth champion James Wilby won a second silver medal in Glasgow in the 200m breaststroke with a sterling last 50 metres.
Out on the track 19-year-old Ethan Hayter added to his gold in the men’s Omnium with a bronze in the Madison with an impressive fightback with teammate Oliver Wood.
Katie Archibald also added a third medal to her European Championship haul with silver in the Omnium.
And Britain’s dominance of the Tollcross Swimming Centre continued when Max Litchfield secured bronze in the men’s 200m individual medley.
Alys Thomas earnt an impressive bronze in the 200m butterfly to cap off another impressive day for Great Britain’s athletes.
Great Britain have moved up to second in the leaderboards after another sterling display in Glasgow, with sevens golds, eight silvers and eight bronze medals.
Uttoxeter swimming sensation Adam Peaty is on course to win four European Championship gold's after helping Great Britain to gold in the 4x100m relay.
The team of James Guy, Georgia Davies and Freya Anderson smashed the European record to win Great Britain’s only gold of the day.
After the race, Peaty said: “The four has been on my mind, it is always is.
“It would be nice to defend all of my titles, but I will go event by event. That was a nine out of ten in the mixed relay.
“Coming back after the world record I was very sore so it is nice to get back to a nice rhythm.”
Elsewhere, James Wilby built on his 100m breaststroke silver with another second-place finish in the 200m variant.
The two-time Commonwealth Games champion edged out in third as Ross Murdoch misses out on a medal by a hundredth of a second.
Max Litchfield also added a bronze medal in the men's 200m individual medley final – finishing narrowly outside gold by 0.92s after a turbulent year with injuries.
And Commonwealth champion Alys Thomas again defied the odds to finish third in the women’s 200m butterfly finals – finishing spectacularly in a time of 2m 07.42s.
Katie Archibald admitted to being disappointed after missing out on a second gold of the European Championships – narrowly being edged out by Dutch rider Kristen Wild.
The Olympic gold medallist said: “Once I realised I didn't have it, I switched off. Then you think you have to get lap gains instead - it was just a bit of a non-race as it became unachievable.
"I'm a bit dejected. I didn't have it.
"I'm excited for the Madison, me and Laura (Kenny) haven't had much training together but what we have done has been really good."
Meanwhile Ethan Hayter’s European Championships continued in good stead with a bronze in the Madison alongside teammate Oliver Woods.
The duo fought back from nowhere to clinch the third spot and earn Hayter a second European Championship medal.
Hayter said: “It’s been better than I could have expected and I'm really happy with it. It's the first time I've ridden with Oliver so we've done pretty well with it.
Unfortunately, Jack Carlin didn’t fare so easily, narrowly missing out on reaching the sprint finals before being edged out of bronze to Dutchman Harrie Lavreysen.
Great Britain just missed out on a podium place on the opening day of the diving in Edinburgh.
James Heatly and Robyn Birch fell just six points short of third place in the mixed team final, settling for fourth with a score of 343.15.
But Heatly, 21, is taking the positives from the opening event and believes it will stand him in good stead for the 1m springboard on Tuesday.
He said: “Nobody likes coming fourth; it’s the worst place to finish to be so close.
“We knew it was going to be quite a close finish anyway so I’m pretty happy with our dives with our next event coming up so I think we’re feeling pretty good.
“It's a case of dusting off the cobwebs now and I’m ready for the next event and we’ll see how that goes.
“I do think it’s a fairly new event and it’s quite enjoyable when you’re diving with your teammate in front of your home crowd too.”
It was a mixed first day for Great Britain’s athletes in Berlin as Nick Miller, Dan Bramble and Daryll Neita all progressed but captain Dai Greene had to pull out of the European Championships with injury.
Greene, 32, was hoping to return to a major games after long-term injury struggles but felt a hamstring tighten in the warm up before the 400m hurdles and was forced to withdraw.
Sebastian Rodger was unable to make it through in the same event but there was better news elsewhere as 2018 Commonwealth Games gold medallist Miller made it to the hammer final.
In the long jump Bramble took the limelight in the absence of Greg Rutherford, with the Brit out of contention after his first two efforts but delivering a big leap at the crucial time with his third jump to progress in fifth.
Bramble’s teammate Feron Sayers missed out on qualification by just three centimetres but there was more good news for Neita in the only women’s event on the first day – the 100m.
Neita ran a time of 11.48s, well below her year’s best of 11.19s but good enough to advance to the semi-finals.
