EUROSTAR has been able to run virtually full trains from London to the Continent for the first time since the pandemic after overcoming border control issues and staff shortages, it can be revealed.The firm has been able to sell almost all 890 seats on its 16-carriage trains to Paris since last month after lifting a self-imposed “cap” on numbers that at one stage left 250 seats per train vacant.This was because French border police – who are based inside St Pancras – and UK Border Force officials, who carry out customs checks, were unable to process enough passengers quickly enough to prevent huge numbers missing their train.
