Great Britain enjoyed their most successful World Championships for 10 years after claiming two more medals on the final day of competition in Berlin.
Silver in the men's 4x400m and for Lisa Dobriskey in the women's 1,500m gave Britain a total of six medals - two gold, two silver and two bronze - the most since seven were won in Seville in 1999 (one gold, four silver, two bronze).
Jessica Ennis and Phillips Idowu struck gold in the heptathlon and triple jump respectively, with Jenny Meadows (800m) and the men's 4x100m relay team taking bronze.
The total of six surpassed by one the target set by UK Athletics head coach Charles van Commenee, who said: "It's encouraging, that's probably the best word. I'm happy."
Dobriskey actually crossed the line third but was upgraded to silver when Spain's Natalia Rodriguez was disqualified in a controversial finish to the 1,500m.
Rodriguez had attempted to overtake leader Gelete Burka of Ethiopia down the inside with around 200m to go, but the pair collided and Burka was sent crashing to the track.
Rodriguez stumbled but was able to continue and crossed the line first ahead of Maryam Yusuf Jamal of Bahrain, with Dobriskey just 0.01s behind.
"It was so close to the finish I just thought 'Don't screw it up, don't come fourth or fifth,'" said Dobriskey, who was fourth in the Olympic final last year after misjudging her tactics.
"The opposite happened to Beijing, I was just running out of petrol in the last few metres. It's quite a satisfying feeling because I couldn't have done any more.
"It was a true championship race with lots of pushing and shoving and, having come through the rounds it really made me believe I'm a true championship performer now."
