The third and final series of Derry Girls will end with a surprise double-length seventh episode set one year in the future, as the band of friends turn 18.
The show - Channel 4 ’s biggest comedy since Father Ted launched in 1995 - is in the middle of its six-part run, which creator Lisa McGee has declared will be the last ever.
But after it ends next month, fans will be treated to an extra hour-long episode which takes the gang to the polling station for the Good Friday Agreement referendum of 1998.
