Think of the French presidential candidate Emmanuel Macron, Ciudadanos in Spain, Nowoczesna in Poland. These are early efforts to reimagine a liberalism which is neither right-wing nor left-wing in the traditional sense.

Donald Trump may undermine some of the traditional checks on the presidency: the press in particular, but also the various government and Congressional ethics bodies, as well as the career civil service.

High national emotions are permissible when a soccer team is playing precisely because they are impermissible at most other times. There aren't, simply, many other places where you can sing your national anthem until you lose your voice without causing a riot. In the context of soccer, flag-waving nationalism - even chauvinistic, anti-foreigner, flag-waving nationalism - is acceptable in Britain.

Globalization has genuinely drained power away from national politicians and people feel it. People in our fast digital age are also frustrated with the comparably slow democratic processes. Many young people - and some old people - want to know, Why does everything take so long? Why can't someone just decide and then move forward?

What's interesting about Navalny is that he has run a - not so much a pro-democracy campaign in Russia, but an anti-corruption campaign. He seems to have access to quite a lot of information about very senior Russians, including Putin.

The Russian economy is about the size of the Italian economy; it's very small, and Russia's military force is larger than it was, because Putin's been investing in it, but it still doesn't compare to that of the United States, and his reach and aim still don't compare.

Khodorkovsky is richest man. And he lost everything when Putin arrested him and took his company away, and essentially took his company away, sold it, and gave it to other people, and enriched them. So, he's a complicated figure as an opposition leader, and people admire him - he was in prison, and he was very brave, and he's written some good things since then, and so on. But at the end of the day, people see him as being part of the corrupt system that has done so much to undermine the Russian system since the 1990s, and I don't know that he can ever be a really popular leader.
