The Self-Denying Ordinance, which was rejected by the House of
Lords in January, is now passed by both houses. It rules that no
member of either House (MP or Lord) can hold military command, and
is directed at forcing aristocratic Parliamentarian commanders like
the Earls of Essex and Manchester to make way for more committed
and radical leaders.
