We are not directly involved in Syria. But we will be working with our partners in the European Union and at the United Nations to see if we can persuade the Syrian authorities to go, as I say, more in that direction of respect for democracy and human rights.

In my view what you can't argue for is a system that is neither decisive nor proportional and can be indecisive and disproportionate at the same time.

We're not getting involved in terms of sending ground forces into Libya. Let's be clear about that. And indeed the UN Resolution forbids that. It says no foreign occupation of any part of Libya.

We have to face the reality of climate change. It is arguably the biggest threat we are facing today.

Governments that use violence to stop democratic development will not earn themselves respite forever. They will pay an increasingly high price for actions which they can no longer hide from the world with ease, and will find themselves on the wrong side of history.

Wouldn't it be better to have a watertight law designed to catch the guilty, rather than a press release law designed to catch the headlines?

As far as I'm aware, everybody in the shadow cabinet accepts that there's a compelling case on climate change and a strong scientific case.
