SIR Paul McCartney owes city taxpayers more than £300,000 after being overpaid for this summer’s Liverpool Sound gig.

Macca’s production company MPL needs to repay £323,046 because the council ended up providing staffing “commitments” for which MPL was paid.

We understand MPL which flagged up the debt to the council.

A document obtained by us reveals the council will end up losing money on the high-profile Capital of Culture event at Liverpool FC’s Anfield stadium.

The balance shows around £1,917,000 was spent staging the event which generated £1,874,318.

Even when Sir Paul pays up, the authority is still expecting to make a £42,800 loss.

The final balance does not include the £323,0000 the council spent on a feasibility study into the scrapped plan to stage the concert in the Salthouse Dock, or the £150,000 donations to McCartney’s Lipa and the Nordoff Robbins Music Therapy Fund.

The donations, the documents reveal, came from “special budgetary provision”.

Today, opposition leaders demanded a clear breakdown of the figures and an inquiry into the financial management of the event.

But the council today claimed the June concert did wonders for the city’s image, equivalent to millions of pounds’ worth of advertising exposure at home and abroad.

A Culture Company spokesman said there were no concerns the MPL debt would not be paid.

He said: “We’ve had to itemise every single piece of expenditure and income and we’ve had to wait for some figures to come back from the club before we could send the final bill to MPL and then their accountants can check there’s been no duplication of costs or fees.

“The repayment should be imminent.”

Labour group leader Cllr Joe Anderson said: “We request the £3230,046 back and thank them for notifying us that we’ve overpaid them.

“The real issue for me is that we’ve put on a concert with world-class acts, not someone off the X-Factor and we still manage to lose money.”
