Germany's Chancellor Angela Merkel has announced that she will run for a fourth term in office, according to BBC on Monday.She told her Christian Democratic Union
(CDU) party in Berlin she expected her toughest campaign yet and would "fight for our values and our way of life".
An election is due to be held next year after four years of coalition with the Social Democrats (SPD).
This year Merkel's poll ratings have slipped because of her refugeesí policy but she retains wide support.
The chancellor, who has been in office since 2005, is also being challenged by the populist right-wing AfD party.
She announced she would stand again after meeting party leaders at CDU headquarters.
Merkel told reporters that the decision to run for a fourth term had been "anything but trivial after 11 years in office".
She added that she expected challenges from both the right and the left of the political spectrum.
If she wins next year's elections, due to take place between August and October, she would equal the post-war record set by Helmut Kohl, who was chancellor from 1982 to 1998.
