The leaders of Plaid Cymru and Welsh Labour clashed over spending initiatives in the Senedd with Mark Drakeford accusing Adam Price of spending money every time he got to his feet.
The men led their parties into a co-operation agreement last year which has seen the Welsh Government commit to a series of spending initiatives including extending free school meals to all primary school pupils and extending free childcare to all two-year-olds. Critics have argued that the only way of funding the spending plans is to take money out of the Welsh Government's core budgets for areas like health, education and transport.
And First Minister Mark Drakeford responded angrily during Prime Minister's Questions when Mr Price argued that the Welsh Government should impose freeze or cap on bus and rail fares as has been seen in other parts of the UK such as Manchester.
