Ekweremmadu in new yam festival in gemany
I think there may be a few assumptions in your question that don't quite add up.
Firstly, Ekweremadu is a Nigerian politician, not a festival. He is a former Deputy President of the Nigerian Senate.
Secondly, the New Yam Festival is a traditional festival celebrated in Nigeria, particularly among the Igbo people. It is not typically celebrated in Germany.
Lastly, Germany is not a country where the New Yam Festival is commonly celebrated. The festival is typically held in Nigeria, particularly in the southeastern regions where the Igbo people are predominantly found.
So, to answer your question, it's unlikely that Ekweremadu would be involved in a New Yam Festival in Germany, as the festival is not typically celebrated in Germany and Ekweremadu is a Nigerian politician, not a festival organizer.
