Orr, 24, was widely considered one of the best young batters in England when he came through as a young player at Sussex. His progress has stalled somewhat since he broke his arm during his first season with Hampshire, but his involvement is a boost for Scotland as they look to build their squad depth.

“It’s really exciting to have this kind of opportunity,” Orr said. “My mum’s side is Scottish, she was born and grew up in Edinburgh. I know her and the rest of our family will be delighted to see me honour my Scottish heritage, and hopefully I can balance these opportunities with my commitment to Hampshire.”

McKerr, 28, was an unused squad member for South Africa at the 2016 Under-19s World Cup but has been playing county cricket as a local for a decade thanks to his British passport. His Scottish heritage is on his father’s side of the family.

Cricket Scotland said that the final make-up of their squad is “subject to confirmation of availability of players currently contracted to English counties”, with Orr potentially unavailable if selected for Hampshire’s County Championship fixture against Somerset.

Both players will remain available for England selection, even if they go on to play for Scotland’s national team in future, with no ‘stand out period’ required between an appearance for an associate member and a full member per in the ICC’s regulations.

“The squad covers lots of bases in terms of spin and pace options and is certainly one that points towards the future,” Steve Snell, Scotland’s head of performance, said. “We are looking at the A team programme with emphasis on providing opportunity but also performances in terms of future international selection considerations.”

Scotland A will face Jersey’s national team in four T20s across the weekend of April 18 and 19, all of them played at Grainville Cricket Ground.

Scotland A squad: Cameron Brown, Lloyd Brown, Finlay Carter, Dan Da Costa, Jamie Dunk, Michael English, Adil Ghaffar, Callum Grant, Jack Hogarth, Ollie Jones, Muhaymen Majeed, Conor McKerr, Liam Naylor, Ali Orr. Coach: Keegan Russell.
