DPD parcel deliveries to homes in the North East will be delayed, the courier has announced.
DPD says increased demand caused by staff walkouts from its rival Royal Mail has led to a "knock on effect" as online stores and businesses switch to alternatives.
Many customers will have to wait an extra day to get their parcels. They include those living in post codes in Newcastle, other parts of Tyne & Wear, Northumberland, County Durham and Cleveland.
