Borders MP Michael Moore wants to enshrine UK funding for developing countries into law - and tomorrow he'll find out if he's been successful.
MPs are due to vote on his Private Member's Bill, which will force the UK government to spend 0.7% of the National Income on helping developing countries.
And he says British aid is vital - both to help, and to set a precedent for other wealthy countries:
Austerity has led to funding cuts for British services. But Moore is confident people will accept that overseas aid is essential, even when times get tough.
And he says dedicating funds to developing countries has practical benefits for people in this country, too.
