Over the coming weeks and months MPs and experts will be poring over the detail of what is in John Chilcot's report. I have all twelve volumes sitting on my desk right now and I aim to read as much as possible. It's crucial that this report doesn't 'put to bed' the Iraq War. The families of the British troops and Iraqi civilians who died deserve better than that. Instead this moment should be a springboard for making the changes needed to ensure that there is never another unjustified and bloody intervention like the one we embarked upon in Iraq thirteen years ago.
We need to hand the power to the people. That clearly means, in the immediate future, a general election. And then it means profound electoral reform - a fair voting system that produces a government that reflects the will of the people. That means proportional representation. It means an elected House of Lords. It means a will to ensure a society in which no one is left hungry, no one homeless, no one stranded without hope of a decent life. It means a society that lives within the environmental limits of our one fragile planet.
As MEPs we are in a grieving process and so experiencing a range of emotions. A lot of the time I feel rage about the poor level of the debate we have just been through and fear about the consequences of the decision we have taken. I am also trying to see positive Green possibilities of operating outside the single market. And quite often I just feel deeply sad.
Before negotiations start, we need to know what we're asking for. That has to mean a General Election - that's the only way we can reach a mandate on a way forward. We'd have a minimum period of months (the earliest practical date would be early November) to debate, discuss, inform voters, who'll then be able to weigh up the offers by various parties.
We have seen things over the past few days and weeks that have raised difficult questions about who we are as British people. And if we are to take Britain forward rather than back, I believe that the time is right for progressive political parties on the left to unite - and to offer a credible alternative to the unholy trinity that is Farage, Johnson and Gove. If Brexiteers are serious about handing control to the British people, then a proportional voting system has to be a priority. And if we are to set about healing the deep divisions in our society which this referendum has revealed, then we need to urgently build a more representative, inclusive democracy.
When it comes to planning to rebalance the British economy away from our dangerous, unproductive reliance on the financial sector, the model of German banking, with regional and local banks that fund and support small and medium enterprises for the long haul has a lot to offer. Of course we can also work with knowledge and skills from other parts of the world outside the EU, but by being already partners, members of the same union, the impetus for cooperation is stronger, the frameworks clearer, the funding available for cross-EU work ready for applications.
For us the power of working together is about job sharing, harnessing the power of collective action at the grassroots of our party and starting a democratic revolution. Time is up for the two-party system - we want to seize this moment to create a new kind of politics that can in turn reclaim and reshape Britain - addressing both the cost of living crisis and the quality of life crisis too.
Britain deserves a factual, broadly focused, debate featuring a wide range of voices: the voices of scientists and green campaigners, small business people and historians, pensioner advocates and youth activists, MEPs who can talk about the work they do and bureaucrats and campaigners who've worked in Brussels who can explain how the EU actually works. That's not what we've had up until now. But it isn't too late.
In every corner of Britain the EU is protecting the environment. Towns and cities blighted by air pollution are finally seeing the British Government forced to act to cut the amount of dangerous particles we're breathing. Precious species in the countryside are protected by tough EU laws which stop overzealous development. Our beaches - many of which were too filthy to enjoy not so long ago - are now cleaner, and our once-polluted seas are safer to swim in too. Young people enjoy a cleaner environment than their parents did at their age - but Brexit risks all of this progress.
I know some will find my decision not to re-stand for the leadership hard to understand, and I've been moved by the generous words of support from many party members and supporters urging me to continue, but I hope that my decision will help make it clear that the Green Party doesn't operate like other political parties, with a steep hierarchy up which many are seeking to scramble, while those at the top defend their positions. We're a team, we work together and support each other.
Our current system means we all get the politics that these users of tax havens pay for. It's now up to David Cameron to break with that unholy alliance - to announce an end to the secrecy regimes in all British-controlled territory, to use the summit he is hosting next month to demand matching action from other nations, and to say that the Tory Party will no longer accept money from donors who use tax havens in their business or personal affairs.
The arguments for a political system that's genuinely democratic, that produces a government reflecting the will of the people that encourages a more constructive, effective politics are overwhelmingly strong. Britain needs to do this. It needs to do it soon. That requires parties, campaigners - the people - to get together and demand the change. Today's one step in that process.
Every summer, at the first hint of blue skies and sunshine, the beach in my constituency in Brighton fills up with people who have travelled from far and wide to enjoy the beautiful seaside. The scenes on those days are replicated across the country. We are people who, despite the inconsistent weather and chilly water - like to be beside the sea. It's easy to forget that bathing in British waters was a hazardous activity not so long ago and that it was action from the EU which cleaned up the coastline.
I believe the people who know first-hand the extent of the problem - the private renters themselves - are the best people to start doing it, and that's why I want to help them to help themselves. Joining forces always makes people stronger, and renters need no longer be the soft touch their landlords take them for.
What's vital now is that young people use our voice to fight for Britain's place in Europe. We know how vast the benefits of membership are; how powerful a union the EU really is. There's a danger, though, that in the coming months this will get lost among arguments about business and finance, and scaremongering over migration.
