Development aid per se is not my goal.

The relief of poverty is.

Aid is a step on that way.

Ending illicit financial flows, closing down tax havens, stopping the corporate abuse of the developing world, ensuring there is tax compliance so that the right amount of tax (but no more) is paid in the right place at the right time happens, all these will make a post aid world. That’s something we owe developing countries. That’s why I concentrate on them.

But in the meantime aid matters:

And the fact that the Tories want to abuse aid by describing military assistance as aid and the promotion of (failed) privatisation as aid is just sickening, as was noted in the Observer yesterday:

As practitioners in the field of international development, we write to challenge the claims that there is a consensus between the parties when it comes to tackling global poverty.

Take the issue of promises on aid. The welcome shift in Conservative policy to back the 0.7% promise in 2005 has been much vaunted by David Cameron, but despite repeated requests they have refused clearly to commit to ensure aid is not diverted for other purposes. Their commitment to the 0.7% target risks looking like political positioning rather than a serious commitment to tackling global poverty.

As concerning as how much the Conservatives will actually spend on tackling global poverty is how they suggest spending it. Access to basic services like health and education are basic rights. Conservative proposals to distribute vouchers for private schools in slums, to create an X-Factor-style competition to decide who gets aid, and a shift to private provision of healthcare, look like crude attempts to export failed ideological or populist policies, against the advice of leading practitioners and aid charities.

Though we would much like there to be, there is no consensus on this issue. Instead, there is a serious choice about whether and how Britain should help the world's poorest people.

0.7% is important.

But not the way the Tories sell it.

That has to be said.
