As has happened to Hillary Clinton, Theresa May has been outed (via secret recordings) as employing double speak when addressing specific audiences.
As per the Guardian:
"Theresa May privately warned that companies would leave the UK if the country voted for Brexit during a secret audience with investment bankers a month before the EU referendum.Politicians more often than not "nuance" their speeches to suit their audience. Were it not for pesky modern technology these nuances could be hidden!
A recording of her remarks to Goldman Sachs, leaked to the Guardian, reveals she had numerous concerns about Britain leaving the EU. It contrasts with her nuanced public speeches, which dismayed remain campaigners before the vote in June."
