prison 'will help' economy, says Welsh secretary A new 2,000-inmate super-prison which will be built in Wrexham will bring economic benefits to the area, the Welsh secretary says. David Jones said the planned jail would also help keep prisoners closer to home. The £250m jail will be built on the Welsh government-owned former Firestone site on the Wrexham Industrial Estate, creating 1,000 jobs, the Ministry of Justice said. The jail should be ready by 2017.
