Students took on the role of 60 delegates representing 18 countries in the Model United Nations event.
All the delegates researched their resolutions before lobbying other delegates in a bid to get their arguments passed.
Students from Winstanley College and Franklin College took part alongside peers from Priestley.
In the end it was Priestley’s Luke Packwood – representing Cuba – who judges felt produced the most convincing arguments of the day.
Georgia Brown and Meredith Day represented North Korea and also impressed with their debating skills.
Former Priestley student Kyle Kirkpatrick returned to college to act as an expert Secretary General allowing extensive debate whilst keeping a firm grip on proceedings.
“All of the committee chairs commented on the excellent questioning and debate that took place at committee level and at the General Assembly,” said Senior Tutor Mark Salmon.
“This is part of our continuing commitment to encouraging active citizenship amongst our students.”
