The so-called "EdStone" stone tablet bearing Ed Miliband's 2015 general election pledges has helped land Labour a £20,000 fine from the electoral spending watchdog.

It was the largest ever imposed by the Electoral Commission after it found the party was missing the right receipts for £123,748 of campaign spending.

The "Edstone" was widely mocked online and there was months of speculation about its whereabouts.

The huge plinth became known as Ed Miliband's electoral tombstone after the party lost the General Election in 2015.

At the time it was unveiled, it was rumoured the stone cost as much as £30,000.

But the missing receipts would suggest the stone cost nearer to £8,000.

Labour omitted two payments amounting to £7,614 in relating to the eight foot block of stone from its election campaign spending return.

This was a breach of the rules which sparked an Electoral Commission investigation.

The party was then ordered to review all of its election expenditure.

Labour treasurer Iain McNicol was found to have committed two offences under the Political Parties, Elections and Referendums Act 2000 (PPERA) and the party has now been fined £20,000.

Its director of party and election finance, Bob Posner, said: "The Labour Party is a well-established, experienced party.

"Rules on reporting campaign spending have been in place for over 15 years and it is vital that the larger parties comply with these rules and report their finances accurately if voters are to have confidence in the system."
