Abolishing the pound for the euro is a bad mistake and will make people feel like strangers in their own country, according to the National Platform.
The group, which opposed the Nice Treaty, points to reservations expressed by many leading commentators and experts about the pitfalls of Ireland joining the euro when the UK remains outside the euro zone.
The group also notes that all independent states have currencies of their own and claims that the EU has taken a giant step towards becoming a quasi superstate under the direction of Germany and France.
"These big states want this directorate formally recognised in the two-club EU provisions in the Treaty of Nice. At the same time, within the euro zone formerly independent states like Ireland become like economic provinces, with no control any longer over the rate of interest, credit or currency exchange rate appropriate to their economic circumstances," it says.
The National Platform also highlights the fact that two thirds of Ireland's trade is with countries outside of the EU, with the US and Britain accounting for the biggest markets. "By signing us up for the euro zone the politicians of Fianna Fβil, Fine Gael, the PDs and Labour have decided to tie the Republic's currency in principle for all future time, with countries with which it does only one-third of its trade."
