I've always wondered about the relationship between the young king and the regent Paul, if they were really cordial and what prompted him to take power by forcing Prince Paul and his family go into exile.
Paul and Peter had cordial relationship indeed...they often stuck together in exile,later in their life!
Paul and his family were forced to leave the country by the British government,as British government were in good relations with Serbian nationalists,who opposed Paul and whose main leader was Bora Mirkovic,Commander of Air Forces.
Months before they were exiled Churchill prepared everything and wrote that Paul and his regency were planning to take the complete power,which was,of course,not true...once he signed treaty of neutrality with Hitler,Paul was forced into exile...
It should be noted that he was left just 4 hours to prepare for his exile!
