The financial problems that most of the world's big economies first confronted in 2007-2008 are still affecting the global economy. No country can face today's challenges on its own. The time when crises were local and isolated in nature is in the past.
After nearly three decades of development activists' and experts' efforts to bring about FTTs, it would be heinous not to use the revenues to contribute to a better future for millions of poor men, women and children.
The UK has tremendous potential for growth powered by high-impact digital entrepreneurship. We need to do everything we can to help our start-ups to scale up.
Sir Ian Blair, the former Metropolitan Police commissioner, wrote a piece in The Times this weekend headlined "Ian Tomlinson is our Rodney King moment". A warning from such a figure of authority must be taken seriously.
Next year Putin and Cameron take the reins of the G20 and G8 respectively. They must show that bringing the most powerful people in the world together can still deliver results for the most powerless.
Hundreds gathered on Copacabana beach in Rio de Janeiro to demand an end to fossil fuel subsidies.

Argentina's continued position around the G20 table is bringing the whole institution into disrepute.
Away from the established centres of power, the world is changing fast. The first meeting of the G20 Foreign Ministers taking place today demonstrate again the need for Britain to continue to build new alliances. For the first time ever the G20 will be chaired by, and held in, Mexico: an indicative sign of the shift which enhances the status of fast-rising economies.
The world has a new global steering committee, the G20 group of developed and 'emerging' economies, which has committed itself publicly to supporting economic growth that reaches the poorest people, and doesn't destroy the environment in the process. At least, that's the talk, but according to a new survey by Oxfam, the walk isn't happening. That matters because the G20 countries are home to half the world's poor people, and account for a much greater chunk of its ecological footprint. Climate change is just the best-known consequence of such failings. Rising inequality also undermines political stability - ask the Occupy movement.
Busan should not just be another photo opportunity where leaders substitute rhetoric for action. This is an opportunity for the British government to really show the leadership they should on international development.
