Newsquest is closing a free newspaper in Wales due to challenges caused by the “significant impact” on the industry caused by the “digital revolution”, it has said.

The weekly Campaign Series newspaper, which covers the Caerphilly and Blackwood areas in south Wales in two editions, has been in print for more than 20 years.

However Newsquest has said it does not have “a sustainable future in print”, and announced in a message to the editor in last week’s newspaper that it was to be the last issue of Campaign.
