Voters in the eastern German state of Saxony-Anhalt are heading to polls on Sunday, where the Alternative for Germany (AfD) party could become the first far-right party to take power at a state level since World War II. Recent surveys place AfD at 40 percent, ahead of the centre-right Christian Democrats (CDU) at 23 percent. Initial results are expected at about 16:00 GMT (6pm local time) on Sunday.
