In a statement the company said yesterday: “Every single parcel and letter is important to us.

"Despite our best efforts and significant investment in extra resource, some customers may experience slightly longer delivery timescales than our usual service standards. 

“This is due to the exceptionally high volumes of mail posted during this further lockdown period, alongside necessary coronavirus-related measures we have put in place in local mail centres and delivery offices to keep our people and customers safe. 

“In such cases, we always work hard to get back to providing our usual level of service as quickly as we can.”
