Markus Braun, the former chief executive of disgraced payments giant Wirecard, refused to answer questions from German lawmakers Thursday over the massive accounting fraud that brought down his firm. "I will not comment on further details and am currently invoking my comprehensive right to refuse to give evidence," Braun said in a statement to the Bundestag house of parliament. Braun, who is in pre-trail detention, added that he would speak with Munich prosecutors "soon". fec/mfp/rl
