Wales last hosted the event in 1958 when they were held in the capital Cardiff. 

An economic study was commissioned following the success of the Commonwealth Games in Glasgow two years ago but Wales' First Minister Carwyn Jones has warned the cost was "too prohibitive" because the British Government would not provide any financial support. 

Wood, however, has promised that it would seek to bid to stage the Games in either 2026 or 2030. 

Plaid Cymru made the pledge in their sports manifesto for the National Assembly election, due to take place on May 5, published to coincide with the start of the Six Nations rugby tournament. 

A bid to bring the start of the Tour de France to Wales would also be launched.

"Twenty sixteen is shaping up to be a fantastic year for Welsh sports," said Wood. 

"With our national football team making history by qualifying for the European Championships, and the Six Nations rugby tournament kicking off this weekend after a strong World Cup for Wales, we must make the most of these occasions.

“Plaid Cymru wants to harness the excitement and ambition that comes with our nation’s great sporting successes, and prove that we can not only produce world-class athletes but also act as a world-class venue for some of the greatest championships and tournaments on earth.

“A Party of Wales Government would want to bring the best international sporting occasions to Wales."

A bid from Wales would probably be centred in Cardiff but also use facilities in other parts of the country, including Newport and Swansea, to ensure the whole nation benefits. 

"We will develop a Commonwealth Games bid with Wales as the host nation in 2026/2030 - something that would not only have the potential to inspire a whole generation to get involved in sports but also secure a welcome boost for our tourism sector," said Wood 

“We will also bid to bring the Tour de France to Wales, for both men and women, and work with sports associations and the tourist industry to identify other opportunities for Wales to act as hosts.

“Plaid Cymru knows that Wales has all the ingredients to be a global success story.

"Under our leadership, the next Welsh Government will ensure that our nation is renowned for excellence, on and off the pitch.”

Wales has several devolved powers from the central British Government in London. 

The National Assembly is currently led by Labour with the Conservatives the second party and Plaid Cymru third.
