I wonder if this is down to a misunderstanding / uncertainty around the bit regarding guests being booked before an election is called?
My reading of the guidelines suggests that they were probably actually ok, given that Heidi was no doubt booked before it was confirmed the election was going ahead. What probably makes it a grey area, and has given them cold feet about the episode going ahead, is that it could be argued that the election was likely to be going ahead anyway. Clearly if it was black and white, they wouldn’t have had her on.
