BBC's Norman Smith adds 

The ruling by the Investigatory Powers Tribunal appears to blow apart the "Wilson doctrine' - a convention set up by Labour PM Harold Wilson nearly 50 years ago to prevent British spies bugging MPs.

The Tribunal states that the Wilson doctrine “has no legal effect” and is merely “a political statement in a political context, encompassing the ambiguity that is sometimes to be found in political statements”.

The Institute of Directors has said today’s jobs and wages figures - showing employment at an all-time high, and unemployment falling to 5.4%, wages rising at 3% year-on-year and youth unemployment also continuing to decline are testament to the way British businesses and employees dealt with the downturn and recovery.

James Sproule, chief economist at the Institute of Directors, said:

John Healey tells the BBC George Osborne's fiscal charter is a political gimmick and doesn't add up to serious economics.  He says that if Mr Osborne was serious about reducing the deficit he would have done so.

The transport select committee is hearing evidence this morning about Operation Stack - the plan to cope with delays and congestion on Kent motorways. BBC Political Editor in the South East, Louise Stewart is following the hearing, here's a taster of the action:

The SNP have restated their position on George Osborne's fiscal charter - they are unequivocally against it.

 Deputy leader Stewart Hosie said Mr Osborne's intention is to "prevent investment in infrastructure projects and it was to make ordinary people in the real world pay the price of these ideological choices".

David Gauke has rejected suggestions the government's fiscal charter is a political stunt to embarrass Labour. The financial secretary to the Treasury said he would rather the opposition supported the plan:
