British books and stationery retailer WH Smith has reported a 6.9% rise in annual pretax profits to £140m, with growth led by outlets at airports and other travel sites. 

WH Smith said trading profit at its more than 750 outlets at travel hubs, including railway stations and motorway service areas, rose 10.3% to £96m and now makes up over 60% of its trading profit. 

Trading profit at its high street outlets was flat at £62m. 

The final dividend was increased by 10% to take the year's total payout to 48.2 pence a share.

The company's travel business has been expanding internationally. It announced the win of six units in both Rome airports, adding another country to its mainland European presence of Alicante and Dusseldorf. 

It also operates outlets at Dubin Airport.

The company also said that travel business sales over the summer benefited from a sharp rise in the number of foreigners visiting Britain. 

Official UK data showed that tourist numbers hit a record in July adding to evidence that the weak pound has made tourism a big beneficiary of last year's Brexit vote.
