The Prime Minister's Office legal adviser should be dismissed for helping former PMO chief of staff Natan Eshel, MK Nachman Shai (Labor) wrote in a letter to Attorney-General Yehuda Weinstein."I ask that you urgently examine the activities and behavior of [PMO legal adviser Shlomit] Barnea-Pargo, when it comes to Natan Eshel," Shai wrote. "It seems like there were serious problems requiring, in my understanding, her dismissal."The PMO and legal adviser Shlomit Barnea-Pargo denied media reports last week that she met with Eshel, who was forced to resign from his post in a plea deal over charges of sexual harassment, to speak about the possibility of him joining coalition talks.Since then, however, Labor leader Shelly Yacimovich released an e-mail she accidentally received from Eshel, which was addressed to Barnea-Pargo and asked her to look into the legality of him being on the negotiation team.
