A marauding hoard of brain-eating zombies that broke into the Houses of Parliament has been forced to move on after failing to find so much as a snack.

Despite the fact that hundreds of politicians were in attendance, the zombies left with empty bellies due to an overwhelming lack of brains.

The rampaging zombies swarmed the Houses of Parliament, tapping their fingers to the heads of each politician that they came across.

Sadly, for the zombies (and the rest of the nation), each tap produced nothing more than a hollow clonk akin to a coconut.

The failed attack is the second close-scrape that British politicians have had in recent days after a group of soul-eaters left the Houses of Parliament just as famished as the zombies.

“British politicians have a natural immunity against any sort of ghoul that feasts on brains, souls or hearts,” confirmed one Conservative MP.
