Britain's Craig Pickering boosted his World Indoor title hopes by defending his 60m indoor title at the Norwich Union International in Glasgow.
Pickering set a world-leading time of 6.57 seconds in Glasgow
The European indoor silver medallist's powerful start saw him set the world's fastest time this year of 6.57 seconds.
Fellow Brit Simeon Williamson took second place while Pickering's training partner Ryan Scott, a guest, was third.
Pickering's win lifted Britain from third to first to snatch victory by just one point from the US and Germany.
Pickering said: "I came here to win. It was very important in front of a home crowd.
"My start was very good but you don't win with just a good start. I am very pleased with the way I held my form right through to the line.
I think I'm a bit ahead of where I was last year so I'm over the moon
"It is great to be in this sort of form already in an Olympic year but my focus now is on the World Indoor Championships."
Jessica Ennis made an impressive start to her season but insisted she would not be vying for a place in the British squad for the Worlds in March.
"No, not this year," said Ennis, who is 22 on Monday. "I'm focusing on a few more indoor competitions but my main aim is getting ready for the summer."
The heptathlete matched her fastest 60m hurdles time of 8.18 seconds and then three times raised her indoor long jump personal best to 6.33m.
"It has been a fantastic afternoon and I am delighted with four personal bests. I think I'm a bit ahead of where I was last year so I'm over the moon."
Sweden's reigning European champion Susanna Kallur claimed the 60m hurdles in a world-leading time of 7.81.

But there was disappointment for local favourite Allan Scott in the men's race as he was disqualified along with German Helge Schwarzer after three false starts.
Scott is the world number one in the 60m hurdles this year but his inexperience appeared to get the better of him in front of his home crowd.
There was better news for Richard Buck, who unleashed a sprint finish to claim an exciting victory over 400m.
The 21-year-old from Yorkshire caught American Jamaal Torrance napping just three metres from the line to win in 47.76.
Chris Tomlinson scored the first British victory of the match in the long jump as he leapt to 7.86m.
Tomlinson had led the competition from the third round but then produced his best jump at the last to make certain of the win.
There were also encouraging successes for the British women with victories for Jeanette Kwakye (60m), Jenny Meadows (800m), Lisa Dobriskey (1500m) and Katrina Wootton (3,000m).
Meadows held off American Sasha Spencer to take the 800m in two minutes 02.89 seconds while Dobriskey led from gun-to-tape to win in an indoor personal best of 4:16.30.
Wootton kept up the winning sequence for the women's side when she held her nerve to take the 3,000m in a time of 9:03.
Kwakye wrapped up the success, roaring to victory over 60m in a time of 7.23 ahead of Sweden's Lena Berntsson and the USA's Sani Roseby.
World 1500m and 5,000m champion Bernard Lagat started his season with an easy win in the 1500m, pulling clear of the field to win in 3:45.89.
Britain's Michael East struggled on his comeback from a knee injury, coming home in fourth place.
