The first version of a newly established Athletics World Cup finished in some disarray at London's Olympic Stadium as the host nation, in with a chance of finishing second overall from the eight countries involved, failed to start the concluding men's 4x400 metres.
There was reportedly no reserve ready to step in when Owen Jones injured himself during warm-up, so Britain was disqualified.
Britain eventually finished third on 155 points in an event which lived up to its billing in terms of quality in some, but by no means all, events.
The United States, overnight leaders, finished as winners with 219 points, well clear of their nearest challengers, Poland, who scored 162.
They thus took possession of the Platinum Trophy.
Jamaica fnished two points behind the hosts in fourth place.
The Athletics World Cup is a two-day team-based international competition inaugurated this year and which featured eight individual nations - China, France, Germany, Great Britain and Northern Ireland, Jamaica, Poland, South Africa and the US.
Each nation enters one male or female into each event, with winners earning eight points down to last place, which earns a single point.
While the event is organised outside of the official International Association of Athletics Federations (IAAF) structures, the IAAF has expressed support notwithstanding the existence of its own four-yearly IAAF Continental Cup event, which next takes place in Ostrava from September 8 to 9.
On June 20 this year, Sky Sports were announced as the host broadcaster within the UK and Ireland.
Each nation is competing for a prize pool of $2 million (£1.4 million/€1.6 million).
South Africa's world long jump champion and Olympic silver medallist Luvo Manyonga produced the performance of the second day of the event as he won with 8.51m, finishing more than 20cm clear of his nearest challenger.
World pole vault champion Sam Kendricks of the US won with 5.83m from the world champion of 2013, Germany’s Raphael Holzdeppe, who managed 5.75.
