Germany's main opposition party has called on Chancellor Olaf Scholz to explain his role in a large-scale tax evasion scam while he was mayor of Hamburg.
Scholz has been dogged by questions about meetings he had with private bank M.M. Warburg in 2016 and 2017. Hamburg officials later dropped demands for the bank to repay millions of euros in tax refunds it had wrongly claimed for share trades.
