A family holiday in Europe will cost up to £500 more next year as the pound collapses against the euro.

Experts say the exchange rate will become one for one in 2018 on current trends.

That means an average week break in Spain for a family of four will be £345 more, an extra £360 for France, £390 for Greece and £495 in Italy.

And that comes on top of big hikes in holiday prices from last year when Britain voted to leave the EU and the pound began to slide.

This summer families paid £255 more in Spain than in 2016 and faced a £360 increase for Italy, according to Lib Dem research.

Leader Sir Vince Cable said: “Families could be clobbered even harder next year than they were this.

“Cheap and easy family holidays to Europe risk becoming a thing of the past because of Brexit as the pound becomes worth less and less.”

Last week the European currency rose above 92p to the £, its strongest showing for eight years.

The euro has rallied more than 10 per cent from its low for the year of 83p in April.

Meanwhile a row has broken out over whether ordinary Brits will ever get to know the ins and outs of Brexit.

Brexit Secretary David Davis is today accused by pressure group Open Britain of trying to do a deal with the EU to stop papers on the Brexit process being revealed.

Labour’s Chris Bryant said: “This smells like a shameful attempt to dodge scrutiny and erase history before it’s even happened.”

Tomorrow Mr Davis will begin his third round of talks with the EU’s chief Brexit negotiator Michel Barnier.

A Whitehall source said: “Both sides must be flexible and willing to compromise. The clock is ticking so neither side should drag its feet.”
