I am not sure which particular letter my hon. and gallant Friend has in mind, but some letters from M. Kuuisnen to the Communist party of Great Britain which were among the documents seized by the police at the Communist party offices in October, 1925, were included in the selection of documents printed and placed on sale in June, 1926, as Command Paper 2682, under the title "Communist Papers." Copies of this publication are still procurable from the Stationery Office.
