Candidates need to stop playing it safe and start playing it exciting, challenging and risky. Build a vision and sell it to Londoners and they'll vote in droves. Keep it dull and safe, and you'll not pull in the vote.
There is a huge amount that a pioneering yet delivery-focussed Mayor could do to improve the supply of affordable housing, spread the living wage, and improve the transition from school to college to work. Sadiq and Zac, over to you.
Ultimately, be it Mr Khan or Mr Smith, we want a London mayor with the brains and guts to tackle the issues affecting Londoners and to ensure its progress as one of the best cities in the world.
Coming together to see how we can effectively lead a political struggle against further cuts to our communities couldn't be more important - please support Diane and help her stop the Conservatives' social cleansing of our city.
If I'm Mayor of London, I want to bring this same kind of passion for people's fundamental rights to City Hall. I can't speak for the other candidates but for me, it's a no brainer - it's part of who I am. I want to be the leader of this great city who gets why it's important we have the right to protest and to free speech, we have the right to a fair trial, and we have the right to privacy.
Listening to concerns from all corners of London at the launch made me all the more certain that London needs a Mayor that has practical solutions to tackle inequality. And giving Londoners of every age, gender, faith and race a voice is a practical way to do it. That's why I'm running to be Labour's candidate for London's Mayoral election.
London is a young, diverse city, and Labour's selection process is the perfect opportunity for people from across all communities to have a say, and play a key role in selecting a candidate who best represents them.
The mayoral contest is bigger than London for Labour, and there are parallels to the Conservative Party when they were in their uppers. Boris Johnson's defeat of Ken Livingstone in 2008 was vital to show the Tories could win again.
Dear Kenny... You and I share a passion for this fantastic city we call home. We both love its vibrancy, its diversity, its history and its culture. There's nowhere else in the world I'd want to call home. But like you, I'm also increasingly concerned that London isn't working for all Londoners.
What concerns me is that the fulfilling of potential that many of mine and older generations have benefited from is becoming more and more difficult, not just in London but across the country. That's why, as Mayor, I will ensure more affordable homes are built, and establish a Living Rent, why I will push the Living Wage and encourage enterprise, and why I will make sure people can afford to get to and from work on reliable affordable public transport. Without these things, aspiration simply gets crushed from the reality of living in London.
There is a real problem for the Labour Party over aspiration and social mobility - and it goes to heart of the major fault lines that exist in its founding... The Labour Party and the trade union movement have a proud record of helping the aspirational. They should be making more of it, not less if it. And Sadiq Khan should be celebrating the social elevation that aspiration and perspiration brought to his life. Without it he would not be a prospective candidate to replace Boris. And we, the public, would not have been able to decide on his merits, or otherwise in the forthcoming mayoral race.
Londoners desperately need a solution to the housing crisis. That's why I'm backing Sadiq Khan for London Mayor - he is the candidate with the most comprehensive plan to fix the housing crisis. The only way to fix the housing crisis in the long run is to increase the supply of new homes. Sadiq has a bold and ambitious plan to do just that.
It simply isn't the case that young people don't care. When given a say over really important decisions on the way the country is run people will turn out to vote. We saw it in the Scottish referendum where people's passion and enthusiasm meant the numbers voting reached almost 90%... Labour is a party that believes in progressive change. We don't accept the status quo. We cannot continue to tolerate such a sharp difference in the numbers who vote between older and younger generations. But we also need to give younger people something to vote for. And there is no bigger issue on the horizon than a say on our whole relationship with the European Union.
The after shock from the general election is still rumbling round the British Labour Party. Prophets of doom variously predict 10 or maybe 15 years of opposition and some even suggest that the party will never recover. Others have begun the post-mortem and taken the first steps towards rebuilding with the start of the national leadership contest.
Forty million voters go to the polls today in what promises to be the closest election in a lifetime. And the ballot paper presents voters with a clear choice. The choice is between a failing Conservative plan and a better plan for working families with Ed Miliband's Labour.
I started Stand up for Labour in July 2012 in a bid to cheer up Labour supporters and raise money for campaigning. Since then, we have managed to raise over £100,000 from events in England, Wales and Scotland. Friday sees Stand up for Labour's 150th event - and last event before the General Election - when we visit Coventry. This is a good time to reflect on the highlights of this comedy fest...
