The new Royal Hospital is set to cost almost double its original budget and won't be finished until 2022, extending a saga that has engulfed Liverpool's two decades quest for a new hospital.
Costs for the new hospital have almost doubled, leaving taxpayers facing a bill of £600m for a hospital that will be finished five years later than planned.
The existing building has proved a difficult home for Liverpool's busiest hospital and bosses have long wished to move to a new site next door.
But despite work starting in 2012 the new Royal is still not finished and staff face three more winters in the old building.
Speaking to members of Liverpool Council's health and adult social care select committee, the hospital's chief executive Steve Warburton said the trust was finalising its business case for the extra work on the hospital.
First hit by delays, then by the the collapse of construction giant Carillion, then by structural defects, the opening date for the hospital has been pushed back again and again.
Here is the two decade long saga of the new Royal so far.
The new Royal: where did it all go wrong?

Hospital bosses say the 646 bed hospital is now six months behind schedule, with June 2017 the new opening date.
They also say Carillion is still refusing to solidify a date when they will be handed the keys.
December 2016: Work halted for the first time
The first real signs of trouble at the site emerge as a cracked beam is found.
After a whistleblower contacted the ECHO about the work stoppage Carillion said an inspection had found the problem and work had been paused as a "precaution".
March 2017: Second delay announced
Carillion blames the cracks found in the building as well as asbestos on the construction site and poor weather as it confirms the new Royal will now not open until the summer of 2018.
The hospital is now 18 months behind schedule.

Months after Carillion's collapse, an ECHO investigation discovers more issues facing the Royal as staff in the old hospital battle to keep an ageing building functioning and work continues to bring the new hospital back on track.
Another ECHO investigation earlier in the year revealed £3m was spent in a six month period simply keeping the empty building maintained, with staff paid simply to go in and turn the taps on and off to prevent infection risk.
September 2018: Wrong type of cladding attached to the building
