It was not a surprise, but Rhun ap Iorwerth did not mention independence at all in his speech in Wrexham on Thursday.

Plaid is trying to appeal to people beyond its base – to voters that might think Wales is better off in the United Kingdom.

But the manifesto ap Iorwerth launched today does talk about independence.

The party says it would not try to hold a referendum in a first term of a Plaid government, but it would set up a “national commission for Wales”.

This would, as well as looking at powers over policing and other items, would lay “the foundations for a future White Paper on Welsh independence”.

A white paper is a government document that sets out a policy to do something – it could be a plan for how Wales would work as an independent country.

When Plaid discussed a white paper in the past party sources made clear it would not be published in the first term of a Plaid government.

Meanwhile BBC Wales was told Plaid would spend £500,000 on this commission – a small sum, although for some of their unionist rivals it will be £500,000 too much.
