In his first speech as leader to Tory conference, the PM also makes pledges on smoking ban and new post-16 qualifications.
"The facts have changed," the PM has said, as he confirmed the HS2 high-speed rail line from Birmingham to Manchester would be scrapped.
Conceding that the public thinks it's time for a change carries significant opportunities - and significant risks. If Mr Sunak can convince voters that he offers a better chance of a new approach to government than Sir Keir Starmer, he may yet arrest the persistent and wide polling gap between the Tories and Labour.
This was accompanied by news that nearly £4bn would be reallocated to transport schemes in six northern city regions. Mr Sunak's speech also included the pledge that the age at which people can buy cigarettes and tobacco in England should rise by one year every year so that eventually no-one can buy them.
It will mean 16 to 19-year-olds will study five subjects instead of three, and some English and Maths to 18. And his speech set out some of the policies - including the cancellation of HS2 - that will form part of the record.
