Labour faces investigation over Ed Stone

Invoices for the campaign stunt, which sparked ridicule, totalling £7,830 have now been submitted by the party.

But the Electoral Commission, which released the documents, said it will be “investigating Labour over what happened”.

Ed Miliband’s manifesto commitments were carved on the 8ft stone in an attempt by the party to show it was serious about meeting its pledges.

Labour blamed an “administrative error” for its failure to include the items with the rest of its campaign spend.

It faces a fine of up to £20,000 if it is found to have seriously breached the rules.
