In recent years I have become, as I have said, more and more involved in work against the incarceration and the persecution of individuals and groups because of their political and religious opinions. I have received a continually increasing number of written appeals for help from individuals and organisations all over the world and almost daily visits from representatives of the latter. I have been unable to travel to distant countries myself, so, in order to have as nearly as possible first-hand objective information, I have been obliged to send representatives to the various countries.
