I want to bribe the king.

Hello,
I used the .deadringer. cheat and gave myself 1 000 000 of Florins. I did this because I wanted to bribe troops. I did this but I encountered the following problem: I can not bribe the king and royal family members.
How can I pass this problem? Is there a cheat to solve this problem? Or maybe I can solve this problem by editing one of the game file or by creating a mod?
Please help me.

Sorry, just not possible in MTW1, all royals are hardcoded unbribable (even though they get VnVs related to bribery).
