UK sales revenues for the winter period were down by 1.9% to euros 735.3 million

Summer forward bookings for Thomas Cook UK are down by 0.6% against the same period last year.
The German-based group saw total sales rise by 1.3% in the half-year ending April to euros 2,436 billion with more than 3.2 million holidaymakers travelling.
