Paul Toner of Shawlands Academy in Glasgow
Mr Toner and Ewan Smith from the High School of Glasgow introduced the Scottish group to the young assembly in fluent French, belying the city's well-publicised problems with modern languages.
Alex Blackwood, chief executive of the Glasgow education-business partnership which supported the trip, said it was "a first step in tackling the low levels of study of modern languages in Glasgow schools".
The partnership also attached importance to European awareness, Mr Blackwood said. For the record, 16 of the Glasgow group agreed that Britain should join the single European currency, 10 disagreed and the rest were undecided.
