Establishment is broken, says Clegg
Nick Clegg is expected to say two years in office have convinced him Britain's "broken establishment is past its sell by date".
The Deputy Prime Minister is due to convene a round table seminar with think tanks and democracy campaigners in Parliament.
The Liberal Democrat leader, who entered an historic coalition with the Conservatives in May 2010, will tell the group - expected to include the Electoral Reform Society, Unlock Democracy and 38 Degrees - he is more convinced than ever of the need to reform.
Opening the Portcullis House meeting, Mr Clegg is expected to say: "I have looked at the institutions of our establishment close up. And I can tell you, I am more determined than ever to see them change.
"Britain's broken establishment is now well past its sell by date."
Mr Clegg will link the Parliamentary expenses scandal, the banking crash, party funding rows and the "sordid spectacle" of phone hacking.
The Liberal Democrat leader, who has faced criticism in the wake of declining poll numbers and local election setbacks, is expected to say Britain "is not broken at all", but will argue: "It is the British establishment that is broken. It is the institutions at the top that have let down the people.
"As political leaders, David Cameron, Ed Miliband and I all have to step up and make sure we seize this moment.
"I really think if we can't tackle these deep problems in the established institutions of our country now, you'd have to wonder if we ever can.
"It is now or never. We have to show real courage."
