In August 1974, Court Line collapsed, taking down Clarksons with at least £7m (£60 million today)owing to 100,000 holidaymakers and possibly twice as much.
In Sep 2008 XL Leisure Group went into administration in the early hours of Friday with debts of £143 million, leaving 85,000 tourists stranded abroad and another 200,000 holidays written off.
In Oct 2017 Monarch collapsed leaving 110,000 holidaymakers stranded in 11 countries.

Are you going to blame those failures on Brexit as well?
