A key component of the UK's first high-energy proton beam machine has been delivered to its new home in Newport.

Proton Partners International (PPI) received the part that will fire the cancer-treating beam at its Rutherford Cancer Centre.

PPI said the UK's "most-advanced piece of cancer machinery" could transform treatment for 500 patients a year.

Currently, only low-energy treatment is available in the UK for rare eye cancers.

PPI's chief executive, Mike Moran, said it was a "great day" for the UK.
