Politics is about everything we do from the moment we get up in the morning to the minute we go to bed at night. It's something everybody and anybody can be involved in.
In the public mind, when they think of politicians, sadly they probably tend to think of men in grey suits doing work behind closed doors at Westminster. I want to get away from the idea.
I don't think politics just happens in Parliament. It happens on the streets and in classrooms.
There are lots of things one can criticise about the European parliament, but it does work pretty well in terms of the speed with which you can vote, the fact that there's room to sit, the fact that there are offices when you arrive.
Reminding oneself that not all rules are good rules and sometimes it's good to challenge them is an important part of being an effective parliamentarian.
We have always been a party that has had policies on everything, from education to the economy to the environment. We have always said that, if you are serious about the environment, then the policies that you need to change most are the economic policies.
I come from a very conventional and non-political background.
On many issues, Jeremy Corbyn and I are in agreement.
My interest was in renaissance literature, looking at how men were writing for women in the 1590s, a time when many women were being taught to read but not to write.
The one thing we have that the other parties do not have is a political integrity. No one thinks you join the Green party because you're politically ambitious, or have your own agenda.
I think if people thought we were just like the other parties and would ditch our policies at the first moment we thought we wouldn't get a majority, then we'd become just like all the other parties.
I think we'd be crazy to do anything to the integrity of our policy package, which is progressive, and really dealing with the key social and environmental issues that we face. We're not about to ditch our commitment to nuclear disarmament, for example, to somehow make ourselves more electable.
To the extent that Bernie Sanders was about building a movement of people where challenging things that up until then were unchallengeable, then absolutely we want to be seen in that mould.
