Royal Mail suspends £5 fine for counterfeit stamps, introduces stamp scanner, and investigates the issue.

Royal Mail temporarily suspends £5 fine for letters sent with counterfeit stamps and investigates the issue. The company has introduced a new counterfeit stamp scanner in the Royal Mail app allowing customers to scan stamp barcodes and check if they are genuine. Royal Mail will still mark letters containing "counterfeit" stamps with a yellow sticker, but recipients will not face charges during the investigation period.
