Legendary UK entertainment publicist Gary Farrow has split with longtime client Elton John over "differences" with the singer's management.

elton johnFarrow is managing director of London's The Corporation, which also reps the Osbourne family among a bevy of UK celebs.

Murray Chalmers PR is taking over John's PR representation, including his Rocket Entertainment Group.

"After some serious thought, and with a heavy heart, I can no longer continue my professional duties as Elton John’s personal PR. Contractual, media, and PR directional differences between Elton’s new management and myself have proved wider than I ever imagined and leave me with little option but to leave," Farrow said in a statement. "It simply remains for me to thank Elton for all the memorable experiences we have shared."

Farrow handled John's recent mishap when a prank caller phoned John pretending to be Vladimir Putin ostensibly to discuss gay rights. The Russian leader later called John.

MCPR added that it also picked up the 2016 NME Awards, Letters Live 2016 and Citadel Festival.

"Working with Rocket Entertainment Group and Elton John is a big personal thrill for me, and confirms my view that we have one of the best artist rosters in the business," said Chalmers, former PR director for EMI Records.
