Here they explain why. The wording on the petition, which you can sign here, is:
We the undersigned believe councillors should not accept pay rises agreed under the new allowance structure voted in by Barnet Council on July 13, 2010.Personally, I think the wording on John Dix's petition is better, more concrete (and longer!). You can sign that here.
We call upon council leader Lynne Hillan to rethink the rise.
And Hendon's former MP Andrew Dismore has a petition as well. You can sign that here.
The more the merrier. Will Lynne Hillan take the slightest bit of notice? No, but David Cameron might.
