Great Britain bravely battled to a surprise bronze medal in the women's 4x400m relay on the final day of action at the World Championships in Helsinki.
Christine Ohuruogu held off Poland's fast-finishing Anna Jesien to clinch bronze in three minutes 24.44 seconds.
Lee McConnell got the British quartet off to superb start running an opening 50.90 seconds while Donna Fraser and Nicola Sanders contributed solid legs.
Russia took the gold medal with ease while Jamaica claimed the silver.
"This is one of the best teams I've been with and I'm so emotional," Fraser said.
"I had to use a lot of my experience in that run and just had to trust my legs."
Ohuruogu appeared to cut across Jesien on the home straight but the 21-year-old insists she was just trying to hold on to her first major medal.
And the Polish team mounted an ultimately unsuccessful protest after the race.
"It wasn't intentional but I wanted a clear run up the home straight," Ohuruogu told BBC Sport. "If I stopped her then I'm sorry."
