The post office’s new chief executive, Nigel Railton, will brief staff on Wednesday on the results of the review, which was launched earlier this year.

The former Camelot boss has been appointed interim head of the Post Office following the sacking of his predecessor, Henry Staunton, in January.

The aim of the review is to put the Post Office on a stronger financial footing.

The troubled organization is currently the subject of a long-running investigation into the Horizon IT scandal. In this scandal, hundreds of postmasters were wrongly sued after faulty software made it look like they had no money in their accounts.

Railton has already told the Post Office inquiry that a new agreement is needed to put sub-postmasters at the heart of the business.

The strategic review is designed to fundamentally change the way the Post Office operates.

The business has 11,500 Post Offices across the UK, many of which are franchises.

Of this number, 115 are Royal Post Offices in city centres, staffed by Post Office employees.

Earlier this month Post Office minister Gareth Thomas said the organization was at a critical point and the government had already launched its own review into what the Post Office should look like in the future.

Business Secretary Jonathan Reynolds told the inquiry on Monday that sub-postmasters did not feel they were paid appropriately for the amount of work they carried out.

He hinted that Post Office branches could step in to fill the gap left by the closure of bank branches on the High Street.
