Unless Labour wins the Anglesey by-election in August, Carwyn Jones will still need the support of at least one of the opposition parties to push through his spending plans in the Autumn. Last year he reached a deal with Plaid Cymru and the previous year it was with the Liberal Democrats.
Kirsty Williams and Leanne Wood hope working together will strengthen their bargaining power. They won't reveal exactly what sort of spending commitments they're looking for, saying they'll agree that after the draft budget is published.
They have given clues though. Kirsty Williams repeated her call for spending to plug the 'funding gap' between schools here and those in England. Leanne Wood emphasised her commitment to job creation. And they added a third area of spending on the health service.
