Travel agent sunshine.co.uk surveyed 1,782 British parents, each with a child under the age of 18, who had been away with their children on a foreign trip in the last 12 months.
26% of parents had let children under 18 drink alcohol when they were on foreign trips. Of these parents, 55% were parents of 15 to 17 year-old, 23% of 12 to 14 year-olds, 18% of 9 to 11-year-olds and 3% of 6 to 8 year-olds.
The main reasons given for allowing their children to drink included that they thought it was legal abroad, it was easier to get away with it abroad, or they wanted their children to have fun on holiday.
Sunshine.co.uk managing director Chris Clarkson said: “Parents that think the legal drinking age differs abroad should always check their facts, because in most places it’s still 18 or 21”.
