 Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists.Mitov received the 152th position on the DS's Choice for a Better Life list and, as the list won sixty-seven mandates, was not re-elected.The DS experienced a serious split in early 2014, with former leader Boris Tadić setting up a new breakaway group that was originally called the New Democratic Party.
