Ireland is the most expensive EU country to buy cigarettes and alcohol in - with prices nearly 87 per cent higher than the EU average.
New Eurostat research also shows people pay just under 30 per cent more for restaurants and hotels compared to most other countries in the bloc.
Meanwhile, the cost of postage along with broadband and mobile phone plans is 40 per cent higher.

"It will send out a clear message to these companies that we're not putting up for being ripped off. There's absolutely no need for it, it does not cost more to run that stuff in Ireland than anywhere else across the European Union.
"So we shouldn't have to pay anymore."
