A further 452 workers have been made redundant following the collapse of construction and outsourcing giant Carillion.
The job losses are in addition to 377 announced last week, taking the total so far to more than 800.
At the same time, the official receiver said on Monday that a further 100 jobs had been safeguarded, adding to the 919 disclosed on Friday.
Carillion, which employed 20,000 people in the UK and was engaged in a variety of public sector contracts, collapsed last month under a £1.3bn debt mountain, with a pension deficit estimated at up to £2.6bn.
The Government’s official receiver, which is handling the liquidation, said on Monday that the latest job losses covered a variety of roles connected with private and public sector contracts across the country, as well as back-office functions.
It said those jobs safeguarded were linked to public sector contracts and most would be transferring on existing or similar terms.
