In 1840 as a result of various abuses and excesses that had plagued the British Post office for many years, Rowland Hill's reforms brought an end to the free franking privilege in 1840 when he introduced the postage stamp to Britain.
[1] Under the Parliamentary Franking System, members of the British Parliament (MPs) were able to send letters free of charge, the cost being borne by the taxpayer.
It was common for members of parliament to give out signed blank sheets of paper to friends and business associates on which they could write letters and mail them at no cost.
[6] Although free franking existed from the middle of the seventeenth century, it was not until 1764, when the Post Office revenues passed from the Crown to the State, that the first handstamp was introduced in England.
In 1764 an Act of Parliament was passed to prevent abuses which included a penalty of transportation for seven years for anyone convicted of counterfeiting hand writing in order to send mail free of postage.
