An interesting sample of "double-cancellation". It is a known fact that a mail that uses Golden Horizon Label is considered "cancelled and correct fee collected" and the no longer require any other form of cancellation.

However, this interesting piece was second-cancelled by machine with PROSTATE CANCER UK, which the postmark itself was different that 2013's PROSTATE CANCER UK. The font and side-switching are very noticeable.

Royal Mail Accounting Codes - September 2011

The Horizon software was changed in late September 2011 to classify the VAT rating of posted items. As a consequence the Machin Horizon labels were printed with two codes indicating the accounting classification and can be found at the end of the lines as follows :
 

Line on Label	Indicator Type
Royal Mail	Accounting Code
POSTAGE PAID UK	VAT rating code

‘Accounting codes' are solely for easy identification of the VAT rate or product combination for each label, where a subsequent refund has to be made, ensuring any VAT is accounted for correctly.
