Stance on Brexit: Truss was a staunch supporter of remaining in the European Union. However, during the recent leadership campaign she has changed her tune:

I was wrong and I am prepared to admit I was wrong. Some of the portents of doom didn't happen and instead we have actually unleashed new opportunities"

This is likely due to the strong support of Brexit amongst the Conservative party base.

She graduated from the University of Oxford in 1996 with a Bachelor of Arts in Philosophy, Politics and Economics. While at university, she was president of the Oxford University Liberal Democrats, advocating for the legalisation of cannabis and the abolition of the monarchy.

  • Both are supportive of the AUKUS alliance.

Likely policy changes
