Edelman is closing its Russia operation and transferring the business to an affiliate relationship with local shop PRT.

Michael Stewart, who heads Edelman's Europe & CIS unit, said "increasingly difficult" business conditions in Russia spurred the retrenchment move.

Kerry Irwin, head of Edelman's Russian unit, is expected to shift to another post within the independent firm.

Edelman has about 15 staffers in Russia, handling accounts such as Unilever, Bayer and Diageo.

Stewart, who was once director of global communications at McKinsey & Co., is confident RPT's integrated communications capabilities will satisfy the PR needs of Edelman clients seeking representation in Russia.

Despite sanctions imposed by the west on Russia for its annexation of Crimea, Stewart said PR demand in the country remains strong.
