The fine is the largest handed out, to date, by the Information Commissioner’s Office (ICO) and the largest since GDPR came in to force last year, eclipsing the £500,000 slap on the wrist Facebook received for its part in the Cambridge Analytica scandal.

The total fine of £183,390,000 equates to 1.5% of BA’s worldwide turnover for the year ending 31 December 2017. BA chairman and chief executive Alex Cruz said the airline was “surprised and disappointed” by the ICO penalty.
