It has now emerged that there is no formal opening date for Hedley Greentree's scheme - Britain's tallest viewing platform.
Portsmouth City Council, the client on the project, has also admitted that it can't set a date for the completion of the scheme's lifts. The project is being built by Mowlem.
This, in turn, is causing delays for the contracted operator, a firm called Heritage, which remains determined to take control of the tower during a peak time. It was keen to open this summer.
'We are still working towards the completion of the lifts,' a council spokeswoman told the AJ. 'But the original completion date for this work has now passed and its hard to say when it will finish.
'We are in discussions with Heritage about when it might want to open the tower, but it had been very keen to open it in the summer and that's not going to happen,' she added.
