Millions of pounds of taxpayers' money are being wasted on loss-making Cardiff Airport, a Tory AM has said.

Darren Millar said the airport "almost looks like a vanity project" and must start generating cash, or be sold.

The Welsh Government bought the airport in 2013 for £52m, after a steady drop in passenger numbers.

It said it took over when "widespread improvements" were needed, and Cardiff was now among the fastest growing airports in Europe.

In addition to the purchase cost, ministers have provided tens of millions of pounds more in loans, now being repaid, grants and further share purchases.

Pre-tax losses in the 12 months up to the end of March 2018 were £6.6m, up on the previous two years.

After five years of Welsh Government ownership, Clwyd West AM Mr Millar believes the taxpayer is getting a raw deal.

"It looks like we've had an airport that has been over-priced and is clearly under-performing," he said.

"Tens of millions of pounds worth of taxpayers' money have been wasted by the Welsh Labour government, and on purchasing an airport which almost looks like a vanity project."

But passenger numbers are now rising substantially, albeit from a low base and still below where they have been.

The airport says securing new operators such as Qatar Airways are key to building new business.

It also says a key performance measure looking at earnings before interest, tax, depreciation and amortisation (EBITDA) has gone into the black for the first time in eight years.

A significant moment, but some investors remain cautious about placing too much emphasis just on that measure.

Justin Urquhart Stewart, co-founder of Seven Investment Management, said airports were often seen as a "status symbol" for cities and countries.

"Be very careful what you are getting. An airport is a shopping mall with a tarmac attached to it for planes to land on," he said.

"So if you're just depending on planes you are going to need a lot of them going through, and currently in Cardiff not a lot are going through."

Travel writer Simon Calder said Cardiff Airport was "not doing brilliantly".

"It's just in the top 20 of UK airports but Southend is challenging fiercely at 21st place," he said.

"Compared with Birmingham, which is about eight times larger, and Bristol, which is six times larger, Cardiff is having a tough old time.

"Those two airports are taking a lot of the traffic that might otherwise go to Cardiff."

Brian Morgan, professor of entrepreneurship at Cardiff Metropolitan University, said passenger numbers at Cardiff Airport were still "nowhere near" what they were 15 years ago.

He said the Welsh Government's decision to scrap plans for an M4 relief road was "disastrous" for the airport.

"The airport needs to expand its catchment area eastwards... but there's a lack of a joined up transport strategy," he said.

"The Welsh Government owns the airport yet have taken a decision to cut off its main route for customers."

While most politicians agree they want Cardiff Airport to thrive, the big question is whether public ownership is the right way to make it happen and, if it is, how long should taxpayers have to wait to get their cash back.

'Recovery'

Cardiff Airport chief executive Deb Bowen Rees said: "Financial performance has continued to improve with a positive EBITDA being achieved for the first time in eight years, alongside an increase in passenger numbers of 9% during that time.

"Cardiff Airport has been through a period of recovery over the last five years and has invested in developing our facilities and in relationships with airline partners with the key objective of creating a sustainable airport business."

She added: "In terms of future ownership, we are focused on driving the sustainability of the business to deliver economic value to Wales."

A spokesman for the Economy Minister Ken Skates said Mr Millar's comments showed "a startling lack of business awareness and pride in Wales".

"We now have an attractive national airport that is amongst the fastest growing in Europe, with passenger numbers having grown considerably and consistently since we took control in 2013.

"This is a period which has coincided with the airport playing an instrumental role in Wales' successful delivery of major global events such as the Nato summit and Champions League final and attracting businesses such as Aston Martin to Wales," they said.
