LONDON—Blue Rubicon has named Patrick Loughran to fill the vacancy left by the departure of strategy head Spencer Livermore to a senior Labour Party role. 

Livermore, who has led Blue Rubicon's Thirty Six Strategy consulting unit for almost two years, returns to Labour to serve as campaign director for Labour's 2015 election bid, alongside shadow foreign secretary and election coordinator Douglas Alexander and shadow cabinet office minister Michael Dugher.

The trio take charge of an election effort that was previously led by Tom Watson, who stepped down from the role amid the Falkirk by-election controversy.

A former pollster and strategy head at 10 Downing Street during Gordon Brown's reign as prime minister, Livermore joined Blue Rubicon in 2009. 

Thirty Six Strategy, the consulting firm that Livermore established to bring political campaign techniques into the boardroom, will now be led by Loughran, a former special advisor to Lord Mandelson.

Loughran joined Blue Rubicon in 2011, spending more than a year at Thirty Six Strategy and also serving as a board director of the main firm.

"[Loughran] has been outstanding since joining us a few years ago," Blue Rubicon founder and senior partner Fraser Hardie told the Holmes Report.
