David Cameron was in Rwanda to launch a policy group's report on global poverty earlier this month. The group's proposals, which may or may not be adopted as Tory policy, include making aid spending more "transparent".

He said all rich countries should end trade tariffs unilaterally and British aid spending should be speeded up. He also said trade rules were "immoral". 

The Conservative policy group, headed by former minister Peter Lilley, published its report, saying aid distribution to poor countries needs to be better scrutinised and more efficient to help them overcome poverty.

In his foreword Mr Lilley said: "It is vital to help promote economic growth which alone can fund their social spending on a sustainable basis.

"Hence our call for renewed emphasis on assistance geared to promoting economic growth - through support for physical and commercial infrastructure and for agriculture on which the majority of poor people depend."

Other recommendations of the report include:

• Increasing the proportion of aid money allocated to infrastructure and trade
• Publishing individual aid entitlements of individual hospitals, schools etc - to help them scrutinise the way it is being spent
• A curtailment of NHS recruitment of doctors and nurses from the developing world - which leaves some countries short of medics
• The British government should help train medical staff and meet part of their salaries where necessary
• The World Bank should track corruption which hampers progress in the developing world
• Aid distribution should be simplified under a single agency
