Sir; Although some may characterise the players in the magazine supply chain as resistant to change, magazine publishers believe no change is not an option.

As the organisation representing magazine publishers in the UK, the Periodical Publishers Association is committed to change for the benefit of retailers, reader consumers and publishers. In short we believe revolutionary change will benefit only one powerful group: the largest retailers.

We believe the changes most seek could be achieved by developing a magazine charter, enshrining retailers' and readers' needs and continuing to guarantee distribution of a diverse, competitive and innovative newspaper and magazine market.

If our market works for retailers and buyers of magazines then it works for us, offering a cost-efficient distribution of product, stimulating readers' interests and attracting advertisers.

We think our distribution system works well on the simple evidence that in the past 10 years, despite huge new broadcast, internet and now mobile competition, hundreds of new magazines have been launched and sales overall have increased.

But we are the first to agree that things could still work better and we are committed to achieving changes that have considerable support among all parties. After discussion with retailers, we have proposed this charter, which will centre on effective self-regulation of the present arrangements, addressing issues of waste, improving transparency and holding wholesalers to account, with the suggestion of an industry ombudsman to oversee the process.
