WH Smith has reached its “strongest ever position as a global travel retailer” after total sales at sites in UK airports, railway stations and hospitals rose by 70% year-on-year in the 20 weeks to 14 January.

Meanwhile travel revenue in North America and the rest of the world increased by 31% and 198% respectively.

Giving an update on its high street stores, WH Smith said total sales were down 2% with flat like-for-likes, which was in line with expectations. The retailer said it maintained good stock availability through the peak trading period and exited Christmas with a clean stock position.

The results meant that total group sales rose by 41% year-on-year in the period and by 20% on pre-Covid levels in 2019.
