A new Athletics World Cup will take place in London this summer, with eight top nations competing.
The inaugural competition is scheduled for 14 and 15 July – the same weekend as football’s World Cup final in Russia and the Wimbledon tennis finals.
Britain and the United States will take part, along with South Africa, Poland, France, China, Germany and Jamaica.
One male and one female athlete from each nation will compete in all field and track events up to 1500m.
The countries will be competing for prize money of $2m (£1.42m) over two evening sessions at London Stadium.
To mark 100 years since British women were given the right to vote, the first edition of the event will see all nations select a female athlete as team captain.
Sell-out crowds expected
UK Athletics chief executive Niels de Vos told BBC Sport he expects the meeting to sell out with crowds of about 55,000 on both days.
“People love medals, flags, countries and that is what they will get. Every event is a medal event,” he said.
He said prize money – largely funded through ticket sales – would be split between teams with $450,000 (£320,000) going to the winners, down to $100,000 (£71,000) for eighth place, with about 45 athletes per team.
“If you were to finish eighth and it was divided by people in your team, that would still be roughly twice what you would get in a Diamond League event, so it will be attractive to the athletes and the federations,” said De Vos.
The previously announced athletics competition ‘The Meet’ has now been cancelled, but its concept of Great Britain competing solely against the United States could be reconsidered in 2019.
