HC Deb 11 April 1968 vol 762 c1570
20. Mr. Onslow

asked the Postmaster-General at how many post offices the "I'm Backing Britain" postmark was taken into use and at how many it is still in use.

Mr. Mason

It was used at 125 post offices throughout the United Kingdom from 9th February until 29th February.

Mr. Onslow

In view of his announcement yesterday, does not the Postmaster-General think that it would be as well if this postmark were withdrawn, or does he feel that any firm claiming in this way to be backing Britain has the right to raise its charges by 8 per cent.?

Mr. Mason

In this case, we chase the largest post offices. Every region was represented. We gave 21 days for the operation, and 84 million letters were franked. That was the Post Office's contribution to backing Britain.
