I don't even pretend we can occupy the Lib Dem holier-than-thou, hands-entirely-clean-and-entirely-empty-type stance. No, we are getting our hands dirty, and inevitably and totally understandably we are being accused of being just like any other politicians.

I genuinely believe that we will look back on today as a landmark for equality in Britain ... No matter who you are and who you love, we are all equal. Marriage is about love and commitment, and it should no longer be denied to people just because they are gay.

I work in lockstep, hand in glove, with the prime minister on these issues, and as we are supportive to the Eurozone so they can sort their problems out, in return they introduce safeguards to ensure precisely what I said: that the single market is not fragmented and that important industries like the financial services industry are treated fairly. Not exceptional treatment, but are just simply treated fairly, on a level playing field within Europe.

For far too long the world's poorest people have seen no benefit from the vast natural resources in their own backyards. It is time to end the injustice where ordinary people are silent witnesses, left to suffer without basic services, as the profits from their countries' assets are hidden and plundered by corrupt regimes.

If the euro zone doesn't come up with a comprehensive vision of its own future, you'll have a whole range of nationalist, xenophobic and extreme movements increasing across the European Union. And, frankly, questions about the British debate on EU membership will just be a small sideshow compared to the rise of political populism.

Growth that lasts does not threaten our children's future. It recognises that our planet is a gift that must be cherished. That tomorrow is our responsibility as much as today.

One of the big changes in politics has been because families, individuals, have felt worried, insecure... worried about the economy, worried about their jobs, worried about their kids' futures... actually the disconnect between the public and media discourse and people's everyday concerns has become bigger not smaller.
