The U.K.'svote to leave the European Union has left more thanthree-quarters of chief executive officers saying they wouldconsider moving their headquarters or operations outside Britain,according to a survey of 100 business leaders by the accountancyfirm KPMG.

Some 72 percent of the CEOs surveyed said they voted “Remain” inthe June 23 Brexit referendum, KPMG said on Monday in an emailedstatement. “While more than two-thirds said they're confidentBritain's economy and their own companies will continue to growover the next year, 76 percent are mulling some form ofrelocation.”

“CEOs are reacting to the prevailing uncertainty withcontingency planning,” KPMG U.K. Chairman Simon Collins said in thestatement. “Over half believe the U.K.'s ability to do businesswill be disrupted once we Brexit and therefore, for many CEOs, itis important that they plan different scenarios to hedge againstfuture disruption.”
