Please note the new start time for this event of 7.30pm.
Speakers on the night include Mail on Sunday reporter Peter Hitchens; Guardian social affairs reporter Amelia Gentleman and freelancer John Arlidge, who writes for the Sunday Times.
With our chair Paddy O’Connell, the presenter of BBC Radio 4’s Broadcasting House, we’ll get the inside story on their nominees’ scoops, investigations and insights and find out what makes hard-hitting political journalists tick in 2010.
We also ask: is investigative journalism under threat from the pressures of the modern media industry?
