Berlin (CNN) -- German Chancellor Angela Merkel's conservative party appeared close to obtaining a super majority in Sunday's parliamentary elections, making it only the second time in the country's history that a ruling party has gained such political control.

Early returns showed Merkel's bloc -- the Christian Democratic Union (CDU) and the Christian Social Union (CSU) -- with a slim 42.2% to 41.7% lead, according to exit polling by Germany's Forsa Institute and released by German broadcaster RTL Television. With those early results, Merkel's party was within two seats of obtaining a super majority.
