Responding to a question from Damian Collins, a Conservative MP on the Culture Media and Sport Committee, on where the limits of investigative journalism lie, Rupert Murdoch went on the offensive and took a dig at members of parliament, several of whom were embroiled in an embarrassing scandal last year for padding their expenses.

Murdoch said that Singapore's model of paying politicians millions of dollars had created a cleaner and more transparent government and one that Britain should emulate.
