BREXIT could hit trade relations between Britain and the United States, with nearly 40 percent of American firms considering moving their British office to the European Union and two-thirds saying the vote is impacting investment choices, according to a survey.

    Food and beverage, life sciences and financial services firms were most likely to consider relocating whilst aerospace firms were the least likely, the survey by law firm Gowling WLG said.

    Nearly all the 533 companies surveyed said they would require some third-party support to deal with the transition as Britain leaves the European Union, potentially risking part of the close transatlantic relationship between the two nations.

    “The strong U.K.-U.S. trade relationship that has been carefully nurtured over the past fifty years is in serious jeopardy,” said Bernardine Adkins, the firm’s head of EU, Trade and Competition.

    “Concerns that Brexit will have an effect on current investment decisions mean this needs addressing now, not later,” she said.

    But U.S. fast-food chain McDonald’s said last week that it would move its international tax base to Britain from Luxembourg after coming under increased scrutiny from European Union regulators over its tax arrangements in the small country.

    U.S. President-elect Donald Trump has also hailed Brexit and said that Britain would not be “back of the queue” for a bilateral trade deal with the United States, opposing comments made by President Obama ahead of the referendum. (SD-Agencies)
