Aggressive seagulls divebombing from roofs are forcing posties in a Cornish town to cancel their rounds over health and safety fears - causing deliveries to be delayed due to 'safety issues.'

Locals in Liskeard have been warned of disruption to their post, as well as to other visitors and key prescription deliveries, as the pesky nesting birds swoop down on postal workers and other house visitors.

The problem has got so bad, Royal Mail has warned them they may not receive their post on time and has started offering residents alternative arrangements - such as a safer delivery address away from the gulls.

A local in Liskeard has shared a recent letter they received from the Royal Mail - warning them of the 'difficulties' faced by postal staff.

It warned that the fiercely protective parent birds mean it is not always safe for staff to approach homes, and that any mail in missed deliveries will be held at local offices until it can be delivered.
