Greek Prime Minister Alexis Tsipras said on Wednesday he may have to call an early election to bolster a parliamentary majority that has been strained by bailout reforms demanded by creditors. About three dozen of his 149 lawmakers have refused to back reforms agreed by Tsipras at a European summit on July 13, forcing him to rely on opposition support to push through the legislation in exchange for a third bailout. "I would be the last person to want elections, if I had the secured parliamentary majority to make it through to the end of the four-year term," he said in an interview with Sto Kokkino radio station.
