From Guardian letters this morning:

Max von Thun decries “more than a decade of disastrous government under the Conservatives”. Mr von Thun may not remember, but no one else should forget that five of those disastrous Tory years were enabled by the Lib Dems voting for & providing intellectual heft to George Osborne’s austerity budgets, the core reason for the social, economic and political disasters we have endured and continue to endure.
