Riding a bicycle is the summit of human endeavour - an almost neutral environmental effect coupled with the ability to travel substantial distances without disturbing anybody. The bike is the perfect marriage of technology and human energy.
It is important that politicians defend their ability to act without fear or favour, and it is in the public interest that they hold ministers and public servants to account.
The Spanish Civil War, Britain was not involved in it. Going back a bit, there was the naval blockade to stop the slave trade in the 19th century; that was morally just. Shame they didn't bother to abolish slavery at the same time.
For the absolute avoidance of doubt, my leadership will be about unity, drawing on all the talents - with women representing half of the shadow cabinet - and working together at every level of the party.
The idea that somehow or other you can deal with all the problems in the world by banning a particular religious group from entering the U.S.A. is offensive and absurd.
I have already said and will continue to say that I won't respond to personal abuse, and I never make any personal abuse, ever, to anybody. I just don't do that kind of politics.
I have always had a very busy life. The difference is that a lot more people are helping advise me what to do, and a lot more people are observing what I do. But in terms of time and working schedule, it is not that different from my normal working week.
Everybody aspires to an affordable home, a secure job, better living standards, reliable healthcare and a decent pension. My generation took those things for granted, and so should future generations.
Sure, I've met with people I don't agree with.
I think NATO is a Cold War product. I think NATO historically should have shut up shop in 1990 along with the Warsaw Pact; unfortunately, it didn't.
Our problem in the 2015 general election was that for all the good stuff that was in the Labour manifesto, we were still going to be freezing public sector wages, cutting council expenditure, laying off civil servants. We were offering 'austerity light' instead of a real alternative.
I have dealt with a pretty interesting mix of young people, many of whom have never been involved in any form of politics at any level who are interested in alternatives to austerity and debt, and older people who left the Labour party, mainly over Iraq, who are coming back in.
I'm not somebody with over-weening ambition.
I haven't had vast amounts of ministerial experience - in fact, none at all. But I do have a lot of experience of people.
I make mistakes like anybody else, I will make mistakes. And you have to reflect on it, and you have to listen to people. That is the key.
We're not going back anywhere, we're going forward, we're going forward in democracy, we're going forward in participation, we're going forward with ideas.
What I find appalling is the intrusive nature towards my extended family.
If there is 'right to buy' for council tenants and housing association properties, then why shouldn't that apply to all tenants? Some landlords are decent, very caring people, but some of them are truly appalling.
Lopez Obrador invokes the appeal of national unity, the revolution of 1910, and the progressive constitution of 1917.
