German election president buhari congratulates angela merkel victory #
I think there may be some confusion here.
Firstly, there is no German election for President. Germany is a federal parliamentary republic, and the head of state is the President, who is elected by the Federal Convention (Bundesversammlung) for a five-year term. The President has a largely ceremonial role and is not directly involved in the day-to-day governance of the country.
Secondly, Angela Merkel is the Chancellor of Germany, not the President. She has been the Chancellor since 2005 and has led a grand coalition government.
Lastly, Muhammadu Buhari is the President of Nigeria, not Germany. He has been the President of Nigeria since 2015.
So, it's not possible for President Buhari to congratulate Angela Merkel on a victory in a German presidential election, as there is no such election and Merkel is not running for the presidency.
