It's Danny Alexander's day at the Lib Dem conference. The chief secretary to the Treasury has got the main speaking slot today and he has been doing the rounds this morning, giving interviews to the broadcasters. As I write, he is on the Today programme. I'll summarise what he has been saying shortly. There was not a single story about the Lib Dems in the early Radio 4 news bulletins, but there's some solid conference coverage in the papers. Here are three of the main stories. The Independent says the Lib Dems want new council tax bands to be introduced so people with expensive houses have to pay more. People with homes worth more than £1m face a rise in their council tax bills as the Coalition Government considers new taxes on wealth. The idea will be pushed by the Liberal Democrats when George Osborne, the Chancellor, tables his demands for more spending cuts. Nick Clegg will demand two or three new council tax bands at the top of the scale as an alternative to the Liberal Democrats' favoured mansion tax on homes worth more than £2m, which David Cameron has blocked. The eight bands on which council tax is based in England - from Band A (up to £40,000) to Band H (over £320,000) - have not changed since 1991 even though property prices have risen sharply. This means that all homes worth more than £320,000 in 1991 pay the same council tax in their local authority area. The Daily Telegraph says Danny Alexander will tell the conference that the Treasury's crackdown on tax evasion and tax avoidance will raise £4bn this year. Concerted action on tax avoidance and evasion will raise almost £4bn for the Treasury this year, Danny Alexander will claim. The figure is twice the sum raised last year, he will say, telling tax dodgers: "We are coming to get you." The Chief Secretary to the Treasury will focus on the issue in his speech to the Liberal Democrat conference in Brighton, promising greater efforts to prevent British residents using foreign tax havens. The Guardian says the Lib Dems would get a five-point bounce in the polls if they were to replace Nick Clegg with Vince Cable. If Cable was leader at an election now, the Lib Dems would gain five points, three from Labour, plus one each from the Tories and the assorted minor parties, the Guardian/ICM poll shows. It would take their rating from the current 14% to 19% - only five points down on the 2010 election result. 9am: Debate on changes to the Lib Dem party constitution 9.45am: Debate on a motion on offender rehabilitation saying private firms running probation services should be subject to the Freedom of Information Act. 10.30am: Speeches from Michael Moore, the Scottish secretary, and Willie Rennie, leader of the Scottish Liberal Democrats. 10.50am: Debate on a motion on inequality saying large firms should have to publish their pay ratios. 12.20pm: Danny Alexander, the chief secretary to the Treasury, delivers a speech. 2.20pm: Debate on an emergency motion on banking saying the Financial Services Authority should impose "the maximum possible penalties" on bankers "found to have breached the trust of their customers." 3.05pm: Speech from Sharon Bowles MEP, chair of the economic and monetary affairs committee in the European parliament. 3.25pm: Debate on a motion saying the government should shelve plans for local or regional pay. 4.20pm: Reports from the parliamentary parties. 5.05pm: Debate on a motion saying the government should abandon parts of the justice and security bill, the legislation allowing intelligence evidence to be heard in secret.
