BUSINESS leaders from across North Yorkshire have been warned that international companies "may think twice about Britain as a place to do business" if a referendum on EU membership is delayed until 2017.

The warning came from the director general of the Institute of Directors (IoD), who was speaking this week at the IoD’s North Yorkshire Annual Dinner at Rudding Park.

Simon Walker voiced his concern that Britain could stumble into an “accidental Brexit” if a vote is not held for up to two years, stating: "We have to accept that the referendum will bring some uncertainty.

"There is a window of opportunity to get reform. My concern is that this window will be left open for too long.

"People may think twice about Britain as a place to do business.

"If a vote on Europe is not held for two years I fear Britain could stumble into an accidental Brexit."

Prime Minister David Cameron has said the referendum will happen by the end of 2017.

Mr Walker, who was previously communications secretary to the Queen and an advisor to Prime Minister John Major, was joined at the dinner by Jon Geldart, Grant Thornton’s executive director, who shared his thoughts on the impact of China on the UK economy and the cultural differences.

Ed Reid, chairman of the North Yorkshire branch of the IoD, said: "Simon is a hugely influential figure in UK business and it was excellent to hear his thoughts on the big issues for our economy, including EU membership and regional devolution. We look forward to welcoming him to Yorkshire again soon."

The IoD has also opened entries for its Director of the Year Awards 2016. To find out more, email iod.yorkshire@iod.com
