Page "Head of state" Paragraph 132

It is usual that the head of state, particularly in parliamentary systems as part of the symbolic role, is the one who opens the annual sessions of the legislature, e. g. the annual State Opening of Parliament with the Speech from the Throne in Britain.

Even in presidential systems the head of state often formally reports to the legislature on the present national status, e. g. the State of the Union address in the United States of America.
