HS2 started as a Labour project, announced in 2009. It has since been hit with setbacks and soaring costs.
It was originally meant to connect London with Birmingham, Manchester and Leeds; but the link between Birmingham and Manchester was scrapped by Prime Minister Rishi Sunak in October 2023.
The new plan is for it to be a high-speed link between Birmingham and London, with a lot of work having already been completed on this section.
