The Cabinet Office has extended the deadline for suppliers to apply to join its G Cloud framework by three weeks to 19 December.
It said that it has received 532 expressions of interest to its invitation to tender, which was published in October, but wants to give even more companies an opportunity to apply.
The £60m framework, which aims to provide government departments with 'pay as you go' IT services, has been designed to be accessible to SMEs, according to the Cabinet Office.
