Parliamentary systems differ, so a ‘one size fits all’ approach will not help to determine the extent to which parliaments have been successful in building on political will and momentum to deliver on the MDGs. Parliaments around the world have played varying roles in contributing to their country’s achievement of the MDGs. Parliaments in developed countries should ensure that their governments honour their commitment to allocate 0.7 percent of GDP to Overseas Development Assistance (ODA), as called for by the Monterrey Consensus. They should also pay greater attention to the quality of aid. But experience suggests that they have often been sidelined in discussions on ODA, resulting in low accountability for the budgeting of aid and its allocation to MDG achievement.
