Don, two simple things give the lie to all you have said.

The government told the Inland Revenue to back off Vodafone about £6 billion.

The government by its new appointee did the deal with Switzerland that netted £2 billion and gave up on £200 billion.

And don't be such an idiot about "voting for a coalition". There was no such option on the paper. The LDs got enough seats to hold the balance of power, that's all.
