Belfast shipbuilder Harland & Wolff is running out of cash, putting hundreds of jobs at risk, the BBC understands.
The firm, famed for building the ill-fated Titanic, is in crisis talks to save it from collapse.

A review looking at options for the shipyard by Rothschild bank is expected to be finished in the coming weeks.
