CentreForum (formerly Centre for Reform) is hosting a discussion forum on LVT at its freethink website.
A paper Tax Shift Now: Regaining our Common Wealth, written by ALTER Chair Tony Vickers for Centre for Reform in July 2005 when the Party's Tax Commission started work, is attracting renewed interest. This is because the Tax Commission is about to focus on LVT in its second year of work. Party Conference endorsed LVT as a key part of the Green Tax Switch in September 2006 and asked for detailed policies to be developed during 2007.
The paper is essential background reading for Conference voting representatives. ALTER's specific proposals to the Commission are summarised in a letter to Vince Cable a year ago which you can see here.
