In Australia, during questions without notice (the equivalent of PMQ), the softball questions from the government backbenchers to the PM (or other ministers) are called a Dorothy Dixer. Is this term known outside of Australia or are there equivalent terms?
This seems to be only used in Australian English.
It is not known in British English, and comments here suggest it is "alien to Canadian political discourse".
In Britain, soft questions and sycophantic questions are common (but tend to get jeered) The government is not supposed to actually plant questions, and Speaker Bercow did warn the government back in 2015.
It is quite common for slang to cross between Australia and New Zealand, but New Zealand discussion groups suggest that they are called "patsy questions" in New Zealand, and the expression "Dorothy Dixer" is not generally used.
