The BBC mysteriously pulled Friday night's edition of Have I Got News For You shortly before it was scheduled to air.
The comedy quiz show usually airs at 9pm on BBC One on a Friday night, but tonight it was replaced with Would I Lie to You? and Mrs Brown's Boys.
The official HIGNFY Twitter account confirmed that it would not air.
They stated that the channel had pulled the episode because of the looming European elections.
The broadcaster said it would be 'inappropriate' for Change UK leader Heidi Allen to be a guest ahead of the vote.

The tweet read: "Sorry everyone. The BBC have pulled tonight's edition of £HIGNFY - no, we didn't book Danny Baker.
"We booked Heidi Allen, a member of a party no-one knows the name of (not even the people in it), because the Euro elections, which nobody wants, may or may not be happening.
"Sorry."
The BBC said that episode of the panel show with Ian Hislop and Paul Merton would be broadcast at a later date.
Some viewers took to Twitter to question the explanation.
One pointed out that Brexit Party leader Nigel Farage had been a panellist on BBC Question Time on Thursday.
Another annoyed fan tweeted: "How on earth does this decision only get made in the hour before the show starts?"
A BBC statement said: "The BBC has specific editorial guidelines that apply during election periods.
Because of this it would be inappropriate to feature political party leaders on entertainment programmes during this short election period, which does not allow for equal representation to be achieved.
"So we will not broadcast the scheduled episode of HIGNFY featuring Heidi Allen, leader of Change UK.
"We will look to broadcast this episode at a later date."
