A director of the developers of London Paramount entertainment resort has unexpectedly left the project.

Fenlon Dunphy was one of the faces of the plans to build a £3.2 billion tourist attraction on the Swanscombe Peninsula between Gravesend and Dartford.

The former chief executive of a listed Russian chemical firm was one of the leading figures in the initial public consultations about the resort due to open in 2021.

He was expected to feature again in a new round of exhibitions on the park showing the latest changes to its masterplan, which are expected to show adjustments to the way traffic will enter the site.

The new consultation, likely to take place early next year, will be the fifth stage of community events run by the resort’s developers, who blamed the delay on the lengthy planning process for the resort, known as a development consent order.

As well as leaving the park’s developer London Resort Company Holdings (LRCH), Mr Dunphy has also resigned from three companies run by Kuwaiti European Holdings.

The Middle Eastern firm, owned by Ebbsfleet United Football Club chairman Dr Abdullah Al-Humaidi, is the largest investor in the project, which is expected to attract 15 million tourists a year.

He continues to run his executive consultancy Oldstone Consultants and is said to be pursuing a number of business interests.

David Testa continues as the chief executive of London Paramount and director of LRCH, which counts only Dr Al-Humaidi and project chairman Steven Norris, the former Tory transport minister, as its other bosses.

In a statement confirming Mr Dunphy’s departure, a spokesman for LRCH said: “David Testa continues as CEO and remains the face of and the driver behind the entertainment resort.

“LRCH’s expert team of consultants appointed to support it in securing a planning application is also still the same.”

KEH Group chief executive Humphrey Percy said: “His input into the project has been greatly appreciated. We wish Fenlon well in the next stage of his business career.”

Mr Dunphy was unavailable for comment.
