<p>Hong Kong's head of public prosecutions quit this week, citing differences with the city's top legal official, and after being sidelined from cases under new China-imposed national security legislation, according to an email obtained by Reuters.</p>.<p>The resignation is the first involving a senior Hong Kong official since Beijing imposed the harsh security laws on the city, and is a sign of discomfort within the government regarding the new arrangements.</p>.<p>David Leung, who heads the city's Department of Justice and who recently led a high-profile public prosecution against pro-democracy leaders involved with the city's 2014 Occupy Central protests, wrote in the email that he could no longer work with Hong Kong's justice secretary Teresa Cheng.</p>.<p>"It is most unfortunate that I do not see eye to eye with the SJ (Secretary for Justice) on the running of PD (Prosecutions Division), and the situation has not improved with the passage of time," he wrote in the email obtained by Reuters.</p>.<p>Cheng's office did not immediately respond to a Reuters request for comment.
