Royal Mail has released details of the Prime Ministers stamps to be issued on 14 October 2014.
Originally shown to the trade as a set of 8 x 1st class stamps (with Clement Attlee the only one not in colour) the set is now revealed as 4 x 1st and 4 x 97p, with the same portrait of Attlee now coloured.
The 1st class stamps show Margaret Thatcher, Harold Wilson, Clement Attlee, and Winston Churchill.
The 97p stamps show William Gladstone, Robert Peel, Charles Grey and William Pitt the Younger.
The stamps will be printed in litho by International Security Printers, in two sheets of 24/48, ie 6 se-tenant strips of 4.
Although the Churchill portrait by Yousuf Karsh is probably the best known it is also probably the most reproduced and it seems a pity that Royal Mail couldn't find a different portrait to the one that they (and Australia and New Zealand) used in 1965.
More details and first day postmarks on our website.

Royal Mail have told me that "We're not planning to do a(n operational slogan) postmark for our Prime Ministers stamps issue."
