No, Tories will do that on their own by pulling the rug out from under the recovery. A good proportion of the public sector signing onto the dole queue, not procuring goods & services from the private sector, general instability and negativity in the market. A potential increase in VAT hurting consumer spending etc etc....
Hospitals turning back into slaughterhouses, schools migrating back to portacabin's etc etc
If we had joined the Euro, maybe it could have been the EU bailing us out rather than us on our own.
