Trinity Mirror has become a founding member of a working group which aims to combat online advertisement fraud.
Trinity Mirror has joined the new group, which also includes the Financial Times and multinational consumer goods company Reckitt Benckiser.
Among the aims of the group, named the Joint Industry Committee for Web Standards (JICWEBS), will be to publish a list of anti-fraud good practice principles for the UK market in July.
It will also oversee the accreditation processes for companies which meet the industry-agreed standards set out to reduce the risk of fraudulent ads being served.
