Gatecrasher - Grand Dame style . London ; London police constables on duty in Downing Street this afternoon, dwarf an an unidentified little old lady who togged up in her finery and who was wondering if she could call at No. 10 for a nice cup of tea and a chat with Mrs Mary Wilson , wife of Britain ' s Labour Prime Minister . Meanwhile , Mrs Wilson was entertaining the wives of the visiting Commonwealth Premiers' to tea at her official home in London for their annual conference which opened at Marlborough House . Evidently , the little old lady imagined that there had been an oversight on the part of Mrs Wilson , and she , as a representative of British womanhood should have been invited . 17 June 1965
