Current UK chief Callum Tuckett has been promoted to Chief Financial Officer and Chief Commercial Officer of the group leaving his current role vacant.

Tuckett has been overseeing UK construction operations since February 2012.

O’Rourke’s two main regional construction directors will cover the role while the search for a successor continues.

A Laing O’Rourke statement said: “Callum Tuckett has taken up the position as Chief Financial Officer and Chief Commercial Officer of the Group.

“Within the UK Construction business, Tom Higgins will support the North and Scotland region with Tommy Drumm in the South region.”

The changes come as former finance head Anna Stewart takes over from Ray O’Rourke as the Group Chief Executive Officer.

Ray O’Rourke is giving-up his current dual role of Executive Chairman and Chief Executive to concentrate on leading the board as Executive Chairman.
