DPD UK has announced that CitySprint will become part of DPDgroup.
This follows a period of growth for CitySprint, which has seen continued demand for its services as businesses require more urgent and time critical same day deliveries.
Once completed, DPD UK's customers will be able to access CitySprint's same day and specialist delivery services in the UK, while CitySprint will be able to offer its customers access to DPD UK's domestic next day and international expertise.
The existing CitySprint leadership team will remain in place.
A DPD spokesperson said: "We are delighted to have received confirmation from the CMA that the planned acquisition of CitySprint has been approved.
“We will be working closely with the CitySprint team in the coming weeks to finalise the transaction and we are looking forward to our future together and the opportunities that will bring."
A CitySprint spokesperson said: “Over the next month we will work closely with DPDgroup to finalise this transaction.
"We are delighted to be joining DPDgroup and excited about the new opportunities that exist for same day services across the expanded customer base.”
