Increasingly governments around the world are experimenting with initiatives in transparency or 'open government'. These involve a variety of measures including the announcement of more user-friendly government websites, greater access to government data, the extension of freedom of information legislation and broader attempts to involve the public in government decision making. However, the role of the media in these initiatives has not hitherto been examined. This volume analyses the challenges and opportunities presented to journalists as they attempt to hold governments accountable in an era of professed transparency. In examining how transparency and open government initiatives have affected the accountability role of the press in the US and the UK, it also explores how policies in these two countries could change in the future to help journalists hold governments more accountable. This volume will be essential reading for all practising journalists, for students of journalism or politics, and for policymakers.
