Royan Jahee
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Royan Jahee appears to be the leader of the "Demand Peace" movement.
After Galactica arrests and interogates Asha Janik for sabotage, Royan Jahee comes forward as a representative/leader of the "Demand Peace" movement, demanding peace talks with the Cylons.
Although Jahee claims a leadership role in the "Demand Peace" movement, it may be that the power base of the movement is shifting to the disaffected fugitive Cylon agent, Gina.
