THE Sunday Herald, in association with political commentator Gerry Hassan, is running a reader competition to find the most striking and memorable photographic images of the referendum campaign.

We invite readers to submit photographs and a summary of up to 50 words about their image. A selection will be published in the paper and in Hassan's forthcoming book about the campaign, That Was The Year That Was.

The deadline for entries has been extended to Tuesday, October 21. Submissions should be sent to: letters@sundayherald.com
