It's interesting that Nick Clegg, in his spring conference speech on the weekend, spoke about how the Lib Dems stand for "a fierce opposition to monopolies and vested interests."
This is the same party that had its autumn 2008 conferences sponsored by Tesco and Microsoft. The party that wants to keep a privatised train network until at least 2025, and that's ok with PFI. To boot, they're in favour of keeping nuclear weapons and the part-privatisation of the post office.
Their shadow climate change secretary, Simon Hughes, gave a conference speech that didn't mention aviation once. Their "pocket guide" to their policies says that "climate change could destroy our way of life" ... could? It damn well will, unless we start doing things about it, like reducing aviation capacity.
Unfortunately, the Lib Dems are just as grey as Labour and the Tories.
