The preferred bidder for the contract to build part of the £850m Swansea Bay tidal lagoon has been named.

Laing O'Rourke, based in Kent, has been chosen for the £200m deal to deliver the lagoon's 1,345ft (410m) turbine house and water flow sluice.

The contract will require up to 500 workers at its peak - the entire project is expected to create 1,850 construction jobs.

The firm says concrete and other materials will be sourced locally.

Laing O'Rourke has named London-based Arup as its lead design and engineering partner for the contract.

Tidal Lagoon Power's director of construction Andrew McNaughton said this announcement is "a major step forward for the project".

Following advanced works and engineering, a fixed price contract will be signed later this year for the main build.
