The wedding ring on my left hand was bought by my grandfather, Samuel Miliband, in Brussels in 1920. I never knew him, as he died when I was one. But his ring was kept by my aunt until it was placed on my finger by my wife Louise 32 years later.

My advice is very simple: if you can win a small battle, it gives you confidence in the political process to take on bigger battles, and so it is very much a bottom-up grass-roots way of doing politics.

I'm a great believer in the Arsene Wenger school of management - which is, you don't worry about the opposition, you just get your own act together.

We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment

Economic dynamism can be combined with environmental and social responsibility. High financial returns can go hand in hand with respect for human rights, and the preservation of the planet's natural resources

Today, the UK must be the pioneer of a new model of economic change, that integrates social and environmental consideration. This is not just a question of values and moral duty. It is about our economy's capacity to sustain itself

Consuming three planets' worth of resources when in fact we have one is the environmental equivalent of childhood obesity - eating until you make yourself sick.
