Sir Paul Stephenson, the former Metropolitan Police Commissioner, is being questioned by a parliamentary select committee over the phone hacking scandal as a day of hearings involving some of the key players in the saga begins.
The Met chief resigned on Sunday night after it was alleged he'd taken hospitality from Neil Wallis, a man who had previously worked for Andy Coulson at the News of The World.
The Independent Police Complaints Commission (IPCC) is investigating how he and John Yates, the former counter-terror chief who stepped down on Monday, handled allegations of phone hacking and corruption.
