We asked the Treasury to explain the actions needed to address the issues that are putting pressure on public finances and risking the sustainability of spending in the long term.

It assured us that fiscal sustainability is the foundation of what the Treasury is looking at, and it needs to look at cost drivers coming up in the future.70
