Fighting against racism and the right wing agenda of the press and the government is essential, followed by restoring funding to ESOL courses. I would also abolish the citizenship test, language tests and swearing allegiance to the Queen. Can you imagine if the hoards of Brits on the coast of Spain faced Spanish language tests and had to take an exam on Spanish history and culture?

Since the Conservative Party privatised the railways, travelling by train has become more expensive and more miserable. If we were in government, the Greens would renationalise the railways and get them providing real public transport again, at affordable prices.

In London, an integrated and affordable public transport system is vital for commuters and everyone who lives in London. In this election, I’ve pledged to cut fares, organise buses better, and build more tram lines. I’ll also link up existing lines to create a full orbital rail ring around London, so that outer boroughs are better linked together, and so that not all people travelling through London by train have to come into the centre and catch the tube between the mainline stations. This will do a lot to help congestion on commuter routes and on the tube during rush hour.

We’re also keen to bring many of the mainline rail franchises serving commuters under the control of Transport for London. We now have ‘London Overground’ providing more services and getting better stations thanks to this process, and we’ll build on this to create a much bigger and better overground system as fast as we can.

The key problem for most Londoners is the incredibly high cost of living, which is why my policies are all designed to save people money, while many will also save carbon as an added bonus. With things like lower transport fares, free insulation available to everyone, more affordable housing, a living wage of £7.20 paid by every employer, and a wider range of local shops and markets providing cheap, healthy food, I’ll improve everyone’s quality of life and cut living costs at the same time.

The olympic logo is odd, interesting, but would look better in Green.

This is a further intrusion of civil liberties, and will inevitably lead to discrimination of minorities by police. Like the spectre of identity cards, it's a further example of the government's distrust and contempt of the people of Britain.

I love the diversity - of people, lifestyles, culture and above all food. I love that within a few minutes of my home I can choose from, among other things, excellent Brazilian, Ethiopian or Phillipino food for dinner.

As public transport is my only way of getting around London, I know what you mean. The problem is that the Tube and rail services were underfunded so massively by successive Tory and Labour governments that our chickens are coming home to roost in the amount of repair work now needed to be done. The failure, as Liberal Democrats predicted, of the Tube PPP hasn’t helped either.

But what I fail to understand is why the consultation between transport operators about which routes close when, and what alternative solution to offer people whose journeys will be disrupted, is so bad. Surely it’s not rocket science for all the operators to sit round one table and plan when the work will take place, and as importantly ensure that passengers can get to what they need to go as quickly as possible.

The current programme of work on the tube is long overdue, but completely necessary, even if it is costing us all a fortune under a PPP we didn’t want. And, unfortunately, the fact is weekends are the best time to do this because they are the least busy days. If I’m Mayor, I’ll make it a priority to keep the works on time, so that London gets the better tube system it needs without delay, and without having to have extra weekends of closures. I will also work on getting trains to run through the night at weekends to make getting home safer.

E."Where do you stand on the suggestion from the recent Government Report that students should be encouraged to swear an oath of allegiance to Queen and Country?"

My views on education are focused on important issues such as reducing classroom sizes and making higher education available to all by abolishing fees and bringing back a proper grants system. I and the Greens do not believe children should be indoctrinated into any ideology; and this includes religion and Monarchy, so no oaths under a Green government.

There is a danger that this election is turning into a personality contest, a sort of “London Mayor Idol” if you like, rather than a proper debate about policies that could deliver better services in the capital over the next four years. Instead you have a candidate running on their old record, a candidate who has never run anything and avoids all discussion of policy where possible, and someone like me who wants a proper debate about how we take London forward. I am serious about the job, and I don’t promise anything I cannot deliver. See my Contract for London for further details.

There do seem to be a lot of policies in this election that are made up in the back of taxis on the way to the press conference. My favourites of these are both from Boris Johnson. He said he will plant just 10,000 trees, when we are already half way through a programme of planting a million trees in London, so he clearly knew nothing about this and just made his number up. The other classic was when he said he’d put bus conductors back on every bus – a great idea, but he underestimated the cost by more than £100 million.

Because the London Greens have worked on the budget for the past four years (since Ken Livingstone has had to rely on our votes to get his budget through since 2004) our policies are much better thought through. We do know what our policies cost and how we’ll pay for them, unlike some other parties’ candidates.

It strikes me as a fairly meaningless gesture.
