The winning ticket holder of last night's €88.5m EuroMillions jackpot has contacted the National Lottery.

There was just one winning ticket and it was sold in Ireland.

"Following last night's EuroMillions Irish jackpot win of €88,587,275, the National Lottery can confirm that the ticket holders have been in touch to make arrangements to collect their prize money."

It is not yet known where in Ireland the winning ticket was sold, or whether it was won by an individual, family or syndicate.

The massive jackpot has been rolling over since 30 December.

National Lottery CEO Dermot Griffin said that it is not yet known where the ticket was sold. 

Speaking to RTÉ News, he said: "Where the winning ticket was sold is still a mystery, but that has not stopped the rumours that it might be a syndicate.

"Whether the winners decide to go public or not, their €88.5m will be ready to collect from National Lottery headquarters next week."

EuroMillions is played in nine countries and this is the third biggest win in Ireland, since it began 13 years ago.

This is the tenth jackpot win for Irish players since 2004.

In 2005, Dolores McNamara from Co Limerick claimed the largest Irish win, taking home €115m.

A ticket sold in Beaumont, Dublin, in 2013 was worth €94m.

Speaking on RTÉ's Morning Ireland, Mr Griffin said there are a lot of syndicates involved in jackpots of these sizes and every winner reacts differently, but he said the National Lottery would provide professional advice to the winner.

Personal finance journalist Jill Kerby advised the winner not to go public.

Speaking on the same programme, she said the winner should be speaking to personal finance advisers, accountants or tax advisers.

The difficulty from now on, she said, will be getting independent, impartial, fee-based advice – not advice based on a percentage of the wealth or each transaction.

Even if the person gives the vast majority of the money away, she said, a single, huge win like this will change your life.

Ms Kerby said there are a lot of issues involved – some legal, some tax.

While Ireland does not have Capital Gains Tax on wins like this, she warned about Deposit Interest Retention Tax on interest earned.
