Private Eye and the Economist have pledged to continue investing in the newsstand after their Brexit issues saw sales uplifts of up to 52%.

In-store sales volume of the July issue of Private Eye covering the EU referendum increased by 52% compared to January to June 2016, according to distributor Comag.

Similarly, The Economist’s edition covering Brexit was up 46% compared to the issues on sale from January to May 2016.

Peter Hilton, head of client relations at Comag, attributed a key element of this success to the performance of independent retailers. He added Private Eye will continue to support independents with a range of PoS material and copy investment.

Sheila Molnar, managing director at Private Eye, said: “Private Eye really appreciates the loyalty of the independent channel, and we are working closely with our distributor Comag to work with them in the autumn.

“Ian Hislop celebrates 30 years as editor on 3 October and we are planning to boost sales through independents.”

According to the publisher, around 20% of the title’s sales goes through independents and symbol group stores.

Michael Brunt, chief marketing officer at the Economist, told Retail Newsagent sales volume was up 9% and 10% year on year in June and July respectively this year.

He said: “We’re seeing this growth continue into August. My focus is not just on volume, but overall profitability, but rather than cutting back the marketing support we give to retailers, we’re maintaining investment.”

The latest report from the Audit Bureau of Circulations (ABC) shows the title’s newsstand circulation was down 3.2% year on year to 90,200 for this period.

Meanwhile, newsstand copy sales for the Economist were down 0.8% year on year to 15,100 from January to May 2016.
