A Plaid Cymru government would bid to host the Commonwealth Games in 2030 or 2034 and would also aim to bring the Tour de France for men and women to Cymru.
In a message on social media, Plaid Cymru said hosting the Commonwealth Games would play a role in "boosting the Welsh economy and the nation’s profile on the world’s sporting stage."
The plan is endorsed by Welsh Commonwealth sprinter Mica Moore:
“As a proud Welsh athlete this is incredible news to me that Plaid Cymru are pledging to develop a bid to host the Commonwealth Games in Wales."
The Plaid Cymru MS for Ynys Môn, Rhun ap Iorwerth, who was behind the island's successful bid to host the International Island Games in 2025 said:
"Hosting the Commonwealth Games could bring not just economic benefits but wider public health benefits to Wales too through improving facilities and inspiring people to take up new sports."
Mr ap Iorwerth also pointed to Glasgow’s “overwhelmingly positive” experience of hosting the Games in 2014 as a possible blueprint, adding that the event contributed up to £740m to Scotland’s GVA in gross terms.
“Hosting the Games would require investment in sports venues and transport infrastructure, creating employment opportunities and leaving a legacy of world-class facilities for Welsh communities to use and enjoy for many years to come.
“I hope that hosting the Games would inspire a new generation of Welsh athletes to follow those already making our nation proud on the world sporting stage.”
