A new 'super-prison' to hold more than 2,000 inmates could be built in North Wales, the Ministry of Justice has announced.
The announcement comes as the Government begins a feasibility study for upgrading the UK's prisons.
The new prison - which larger than any facility in the UK - is likely to be located in North Wales, the North West or in London.
Four new 'houseblock' prisons will also be built - one of which will be situated at the HMP Parc site in Bridgend.
