Ethics in journalism are always under growing scrutiny but perhaps never as close as today. Thomson Reuters is hosting a debate at its London offices to address current questions including the following:

–When is a potential story so important to the public interest that it’s ethical for a journalist to pay for information?

–Has fact-checking and editing become less of a priority in an age of cost-cutting and “personal” journalism? What are the consequences for news organisations’ commitment to accuracy and freedom from bias?

-Are Western standards of news ethics and standards necessarily correct? Should there be a global standard for what constitutes proper journalism ethics?

–Which is more ethically challenged: Journalism practised by state-run news organisations or that practised by news organisations owned by large corporations?

Ray Snoddy will be chairing the event and the evening will be introduced by Dean Wright, Reuters Global Editor, Ethics, Innovation & News Standards. And on the panel will be: Anne McElvoy - London Evening Standard; Joe Lelyveld - Pulitzer Prize winner and ex-NYT editor; Marwan Bishara - Al Jazeera; Sean Maguire - Global Editor, Politics and General news, Reuters.
