 Election days for the Bundestag and the European Parliament are also flag days in some states, in addition to other state-specific flag days.The public display of flags to mark other events, such as the election of the president or the death of a prominent politician (whereupon flags would be at half-staff), can be declared at the discretion of the Federal Ministry of the Interior.When flags are required to be flown at half-staff, vertical flags are not lowered.
