Getting found out

In my time. I have done plenty of public speaking, and it's never easy.  So I can sympathise with the Prime Minister in her difficulties:

Theresa May had 15 minutes to impress European Union leaders with a new way out of the political morass that has become Brexit.

Instead, the British prime minister came across as nervous, speaking too fast for an audience of non-native English speakers. At the end of her pitch in Brussels, no one was any wiser as to what the U.K. was bringing to the table other than a familiar serving of warm words. May left her confused counterparts to dissect her presentation over a fillet of turbot.

Nevertheless, you expect better of a Prime Minister.  I cannot imagine that Harold Wilson, Jim Callaghan, Margaret Thatcher, Tony Blair or Gordon Brown would have been similarly troubled.
