Cardiff has been linked with a bid for several years now having last hosted the event in 1958, when it was called the British Empire and Commonwealth Games.

Last year's event in Scotland was widely praised as the best Commonwealth Games in 84-year-old history of the event.

The economic benefits of hosting the Games remain unclear, however.

A report published last week by the Scottish Government to coincide with the first anniversary of the Opening Ceremony of Glasgow 2014 revealed that it contributed £740 million ($1.2 billion/€1.1 billion) in national gross value added and £390 million ($609 million/€554 million) to the city between 2007 - when it was awarded the event - and 2014.

It is claimed, though, that the £425 million ($663 million/€603 million) of public money poured into the Games would have had roughly the same economic impact if it had been spent on other things.

The social legacy of hosting the Games also remains unclear. 

Earlier this year, Wales' First Minister Carwyn Jones claimed he would like his country to host the Commonwealth Games but the cost was "too prohibitive" because the British Government would not provide any financial support. 

“We believe that a decision regarding whether or not to submit a bid for Wales to host the 2026 Games must be based on evidence and lessons learned from previous events, as well as a full assessment of the benefits and economic feasibility of staging the event," a statement from Commonwealth Games Wales said. 

“As such, we look forward to seeing the economic impact study for Glasgow 2014.

"Should there be a Welsh bid in the future, Commonwealth Games Wales would be one of the main partners responsible for preparing the bid.

“In fulfilling our role, we would engage with the Welsh Government and a wide range of other stakeholders and communities across Wales, including politicians from all parties, to make sure that a strong case was presented for bringing the Games to Wales.

“Wherever future Games will be held, our focus will remain on providing an outstanding performance environment for elite Welsh athletes and continue to raise the bar in terms of medals and achievement at Commonwealth events.”

If Wales does decide to bid, it could face stiff competition from Papua New Guinea.

They are seriously considering launching their own bid following the success of the Pacific Games in Port Moresby earlier this month.

Any bid from them would be an attractive option to the Commonwealth Games Federation as no Pacific island has ever hosted the event before.
