From an American perspective they are more akin to the Democrats: they support gay marriage, support legal abortion, don't support reintroducing the death penalty, support public health care (to some extent), generally support public education, do at least claim to accept that environmental issues are a concern (although we do have an environment secretary who denies climate changes science…). They support giving benefits to at least certain groups in society (pensioners, land owners) and accept the need to provide some level of support for the disabled, unemployed, single parents and so on. They made commitments to maintaining the level of foreign aid. For all their talk of pulling out of the European Convention on Human Rights they have not actually done so. So they have a lot of policies that your typical Republican would be fairly disgusted by.

I wouldn't vote for them myself of course…
