Sprinter Beth Dobbin and long jumper Lorraine Ugen will spearhead Britain’s team at the Athletics World Cup at the London Stadium on 14-15 July.
Dobbin, who will run the 200m, and Ugen are among 21 British champions from last weekend selected for the inaugural edition of the eight-nation event.
High jumper Morgan Lake and hammer thrower Sophie Hitchon are also named.
World Indoor 60m hurdles gold medallist Andrew Pozzi will also compete at the 2012 Olympics venue.
Commonwealth hammer gold medallist Nick Miller and Wales’ former world 400m hurdles champion Dai Greene also won selection in winning their events at the British Championships last weekend.
But the likes of 100m winners Reece Prescod and Dina Asher-Smith, fellow sprinters Zharnel Hughes and Adam Gemili and middle-distance star Laura Muir will all be missing.
UK Athletics chief executive Niels de Vos believes the event “will be a success”, despite clashing with the Wimbledon finals, and football’s World Cup final on Sunday, 15 July.
“It’s the first time it’ll be done – the Ryder Cup and Rugby World Cup have come an enormous distance and this can do likewise over the next 10, 20 years,” he said.
“I don’t think there’s much of a clash (with Wimbledon or the football World Cup) with the audience who are going to buy tickets, and there’s no television clash at all.
“Those (athletes) that aren’t there we always knew weren’t going to be there. We only announced the event in February and four or five had already signed contracts to do Diamond Leagues that weekend.
“People sometimes are uncomfortable with the new, and look for the weakness, but there’s so much to be pleased about.”
Five athletes will make their senior British debuts, including Scottish record holder Dobbin, who smashed her own personal best in Birmingham to make her the fastest Briton over 200m this summer.
“It has been a crazy season so far for me but it feels great to be handed my senior British debut,” she said.
“If you had asked me at the start of the season if I would be in this position, I would have probably said no but I knew if I started running well I could start to achieve what I have done.”
Other newcomers include fellow Scot Jemma Reekie, the European junior 1500m champion, European Under-23 100m champion Ojie Edoburun, and European junior triple jump bronze medallist Naomi Ogbeta.
The British team will compete against the United States, South Africa, Poland, France, China, Germany and Jamaica.
