Rotblat informs BR of what has been going on with Pugwash, specifically regarding his suggestion at the beginning of January to hold a conference discussing the Geneva deadlock on the ban of tests, which was not met favourably. "However, two weeks ago, all of a sudden, I received a cable from Topchiev saying that the Russians agree now to such a conference. In the meantime two Americans, Leghorn and Wiesner, went to Moscow and one of them rang me up not long ago saying that the Russians are now very enthusiastic about the conference on a test ban." He writes that the suggested conference would be no later than the first week in May and in London.
