Time is running out for the government if it is to find time in the legislative programme for what is sure to be a hotly contested bill to reform the House of Lords. But having failed to change the voting system in the Commons last year, the Liberal Democrats are growing restless for a reforming constitutional policy change they can call their own.
In the studio this week: Meg Russell, an expert on the House of Lords and deputy director of the Constitution Unit in the department of political science at University College London. Joining her is Dr Evan Harris, a former MP and now a Liberal Democrat activist and agitator on constitutional reform and health policy. The Guardian's Michael White completes the line-up.
Also this week: as Lib Dem peer Shirley Williams consents to the NHS bill, we look ahead to next week's spring conference, where trouble is brewing over a health policy many feel goes way beyond the coalition agreement.
And finally, our Washington editor Ewen MacAskill explains why he's heading to Ohio for next week's "Super Tuesday" primaries in the Republican nomination race to take on Barack Obama in November's election. He says the Mitt Romney is likely to cement his position as the front runner.
