PARCELFORCE Worldwide is to open a new depot in Cornwall, creating 60 new jobs, as part of a £75 million investment programme.
The delivery business, which is part of the Royal Mail Group, says it will create a total of 1,000 new jobs in the UK over the next four years.
A destination has not yet been chosen for the new depot, which would open within the next two years.
The majority of the jobs would be for drivers to collect and deliver parcels.
Royal Mail Group's chief executive Moya Greene said: "Our £75 million investment is part of Royal Mail Group's strategy to grow its parcels businesses in the UK and overseas.
"Our strategy is to convert the rise in parcel volumes into profitable growth. That means becoming a more customer-focused company being run on commercial lines and investing in new, vital technology.
"The investment will enable Royal Mail Group's express parcels' business to meet the rapid growth in demand in the business-to-business, business-to-consumer and consumer-to-consumer markets."
The UK express parcels market is currently worth £5.8 billion a year and carries around 1.1 billion items.
The expansion is part of Royal Mail Group's strategy to grow its parcels businesses in the UK and overseas. In the last reported financial year, Royal Mail Group's parcels businesses accounted for 48 per cent, or £4.2 billion, of its total revenues, excluding Post Office Ltd). Royal Mail Group saw its UK parcel volumes increase by 6 per cent in 2011-12.
