Royal Mail has been criticised for offering an “unacceptable” performance over the crucial Christmas period after it failed to deliver letters and cards on time to about 16 million people, Citizens Advice found.
The consumer watchdog, which carried out research into Christmas deliveries, said that figure was 50% higher than in 2024, and the highest level over the festive period in five years, excluding when Royal Mail was hit by strike action in the run-up to Christmas four years ago.
