Independent media commentator Stephen Glover today criticises The Guardian for inviting advertisers to pay money to influence editorial in sponsored supplements.

He has received a copy of a letter sent out by Wendy Miller, public sector manager of the Society Guardian supplement, offering sponsorships of a supplement on the future of public services at £15,000 each.

She says that the sponsors would get “significant branding space as well as input into the editorial direction and content of the project”.
