VisitBritain Director Patricia Yates said: “Tourism is one of Britain’s most valuable export industries and this continued growth demonstrates the industry’s increasing importance as a key driver of economic growth across our nations and regions.
“The tourism industry is making a compelling case to be one of the industries included in the government’s industrial strategy to ensure Britain continues to compete globally.
“We have already revised our forecast upwards for 2017.”
