Scotland’s The National newspaper will produce a Welsh edition for Saturday’s pro-independence march in Merthyr Tydfil.
Some 2,000 free copies of the bilingual edition will be distributed to those taking part in the march organised by All Under One Banner Cymru.
The eight-page newspaper will feature news and sport, as well as an article by Adam Price, the leader of Plaid Cymru.
The National’s editor Callum Baird said: “No-one paying attention to politics in today’s dis-United Kingdom could have failed to notice the change in Wales.
“The National is delighted to produce this special edition and reflect that change in a media landscape where independence supporters are often poorly served.
“We’re sure the march will be a great success.”
The National launched in 2014 and has a total circulation in Scotland of near 10,000 copies.
Plaid Cymru leader Adam Price said that he hoped that it was a first step to launching a newspaper such as The National in Wales.
“We wish we had a newspaper like The National publishing in Wales,” he said. “Why don’t you come and join us? The water is warm.”
The march in Merthyr Tydfil will be the third independence march in Wales, after previous marches attracted 5,000 people in Cardiff and 8,000 in Caernarfon.
