A family from a village outside Dublin has claimed a €175m (£152m) EuroMillions jackpot after stashing the winning ticket in an Argos catalogue under a mattress.

The family syndicate spent the day digesting and celebrating the news that it had won Ireland’s biggest-ever jackpot.

“This is unbelievable. It will take us some time to get our heads around this win and to organise ourselves,” said a spokesperson for the family, which has not been named.

“We are a very close family. We meet every week and we take holidays together every year. This is a dream come true for us. We don’t want this to change our lives. What is so exciting is that we will be able to share this money with children, grandchildren and extended family members.”

The lucky ticket was bought at a store called Reilly’s Daybreak, in Naul, a village north of Dublin, prompting jubilation among staff and customers.

The winning numbers 01, 08, 18, 19, 39 and “lucky stars” 07 and 09 in the Europe-wide lottery were drawn in Paris on Tuesday night.

A syndicate spokesperson said the ticket had been kept in an Argos catalogue under a mattress for safekeeping until it was delivered to the Irish national lottery headquarters in Dublin.

“We need time to let this news sink in and to prepare to collect our winnings. We are a normal family and we don’t want this to dramatically change our lives.”

Miriam Donohoe, a spokesperson for Ireland’s Lotto, said the ticket-holder was “surprising calm” in the initial phone call claiming the win.

It is the biggest Lotto jackpot won by an Irish ticket-holder.

A couple from Moira, in County Down, Northern Ireland, set the island’s previous EuroMillions record in January with a £115m jackpot.

Frances and Patrick Connolly said that upon realising they had won, they sat in silence and stared at each other for 10 minutes, then made a cup of tea. They told a press conference they would share the prize with 50 friends and relatives.
