EU referendum, brexit and the aftermath

On the environment, I think you need to look what on balance was achieved while a minority in coalition. Such as the Green Investment Bank and the record levels of RE investment over that period. Jo Swinson's voting record is mixed, and not as strong as it should be. However, I don't think cherry-picking the forestry vote is useful.

On the voting record as a guide to policy, I agree you need to look at it, but it's important to remember we have an adversarial party system, as well as bills being made up of a number of elements*. MPs generally vote with or against the government on party lines.

*e.g. JC has voted against raising the basic income tax free allowance. It seems unlikely it's because he thinks poor people need to pay more tax.
