For our show today we've teamed up with the online campaign group 38 Degrees to bring you an in-depth look at the issues their members wanted to raise with the authors of each party's manifesto.
Joining us from a studio in Gateshead we have Labour's manifesto author Ed Miliband, the climate change secretary.
From his constituency in Inverness we have Danny Alexander, the author of the Liberal Democrats' manifesto and Lib Dem chief of staff.
And with us at Guardian HQ is the shadow culture secretary, Jeremy Hunt.
Over 10,000 votes were cast by members of 38 Degrees on the topics most important to them and as a result the party spokesmen are grilled on a "Robin Hood" tax, lobbying, climate change, the digital economy bill, banking reform and Trident.
Also in the studio Hannah Lownbrough of 38 Degrees was monitoring your tweets in real time.
Leave your thoughts below. We're back at 5pm tomorrow.
