The Princess of Wales has announced that she has completed her course of preventative chemotherapy following her cancer diagnosis.

In a video statement, she conveyed cautious optimism about resuming a limited number of public engagements by the end of the year, although insiders from Kensington Palace emphasised that her return to royal duties would be gradual, with her recovery taking priority.
