Following the earlier news that Liverpool has been cut from the shortlist for the new Channel 4 HQ, the broadcasters has now announced only Leeds, Manchester and Birmingham remain in the running.
Bristol, Cardiff and Glasgow have been cut from the HQ list but are now being considered for the proposed new creative hubs as are the three cities in the race for the new HQ.
In terms of the shortlist for the creative hubs, Belfast, Brighton, Newcastle, Nottingham, Sheffield and Stoke-on-Trent have all been cut.
The broadcaster said each of the cities was carefully assessed against Channel 4's "vision and objectives" for the new locations.
It will now enter into "detailed discussions" with the six shortlisted cities over the summer.
Chief commercial officer Jonathan Allan said: "Our visits to the 13 shortlisted cities over the last month were incredibly inspiring and I’d like to thank all of those involved for the huge amounts of creativity they demonstrated and the excitement for Channel 4 and what we could achieve together.
"We have again had to take some very difficult decisions on which cities to take forward to the next stage, but we believe the six cities we have selected are best able to deliver against our vision and requirements for the new national HQ and creative hubs.
"The national HQ and creative hubs are only one part of our '4 All the UK' plan, which has at its heart, a commitment to significantly increase our Nations and Regions contend spend by £250 million over the next five years.
"We therefore look forward to working closely with all those cities and regions that have been involved in the pitch process, as we look to catalyse that spend and support digital and production companies right across the UK."
