"We have a prime minister completely dependent on National Rally," said Ms Castets who complained that she, like millions of French voters, felt betrayed and that the president had in effect ended up governing with the far right.
In practice, given the announcement of a significant increase in employers' National Insurance rates in October, the government's view is that it would have to mean spending restraint - Darren Jones, the Chief Secretary to the Treasury, practically said as much in the Commons today.To be clear, spending restraint would not necessarily mean spending cuts, just much lower spending increases than would otherwise happen.
This is where economics could collide with politics fast.It's all very well for the Treasury to take measures to soothe the bond markets, where government debt is traded.But just because a strategy is deemed the most economically viable available, that doesn't mean it is politically viable in a Labour Party made up of MPs who have spent the past 14 years decrying Conservative austerity.
Many Labour MPs, among them cabinet ministers, believe there is little fat left to trim from the state.They were already anxious about a tough multi-year spending review, expected to conclude around June, before borrowing costs rose.
There is almost a risk of a paradox: that any acts of spending restraint visible and significant enough to calm the markets might, by definition, be too visible and too significant to fly politically among Labour MPs - especially after the controversy of the cut to the winter fuel payment for pensioners.
Labour figures argue that successive Conservative governments dealt with similar problems by piling the most painful spending measures towards the end of five-year forecast periods - hoping that by the year at which those "pencilled-in" measures were reached, circumstances would have changed."There is no justification for compulsory redundancies at this time. Rather than slashing jobs, university leadership should be joining us in demanding proper funding for the sector."
A spokesperson for the University of Derby said they have had to respond to "well-publicised challenges facing the sector".They added the university "remains committed" to investing in high-quality, sustainable research.
"We must ensure our resources are channelled in support of an exceptional student experience and towards research that has the greatest impact in the UK and around the world," they said."In this context, the university is considering plans around the structure and resourcing of our research.
