On Sunday, 3 May, Ed Miliband unveiled an eight foot tall stone in which Labour's six general election pledges had been carved.

Miliband said the rock will be installed in the garden of Number 10 to act as a reminder of Labour's promises during the election campaign… if Westminster council's planning department permits.

Ed's Stone was soon met with ire from professionals, such as Simon Blackwell, one of the minds behind the political satire The Thick of It.

It didn't take long for other social media satirists to leap on the act.

But Miliband wasn't the only target:

It also possible that Labour looked for the SNP for help with this PR stunt, as they will end up doing after the general election.

On the other hand, Ed's Stone could have had a more literary inspiration – assuming that someone confused "inspiration" with "warning from history".

But if things don't go Labour's way on 7 May, this stone may be more appropriate.
