Three of the signatories have strong links with the Institute for Fiscal Studies - Costas Meghir is the Deputy Research Director, Orazio Attanasio is Director of Development Studies and Tim Besley is a Research Fellow there.

I have argued for some time that the Institute for Fiscal Studies is little more than a Tory front. Such blatant argument, openly anti-Labour and openly pro the deluded policies of George Osborne is clear evidence of the fact.
