Teenage twins from Parsons Green are to travel almost 10,000km to help build a school for children in a remote valley in Peru.

Amelia and Matilda Buttler are part of Hammersmith and Fulham’s RAF Air Cadets Squadron.

The 15-year-old pupils from Lady Margaret School passed a tough London-wide selection to join the expedition.

31 Air Cadets are heading out to Peru, with Amelia and Matilda the youngest taking part.
