DIFFERENCE BETWEEN AMBASSADOR AND HIGH COMMISSIONER
Well Mr.Naeem , According to my information the functions these two individuals perform are the same. There is no difference. I understand that both are of the same rank.There is only one ambassador from one country to another; where he sits is his
'embassy' in host country's capital.
He has many 'consulates' in important cities of the host country, each manning a 'consulate'.
Between a pair of (formerly 'British') 'Commonwealth' countries, Ambassador and consul are replaced by (designated as)
'High Commissioner' and '
Deputy High Commissioner'.
DIFFERENCE BETWEE FEDERAL AND STATE MINISTER
The Federal ministers are representing entire nation with responsibilities to govern on behalf of his government about his department. State ministers are to look after state affairs under the federal ministers. unless mentioned independent charge,
state ministers are under federal ministers.They will be assisting the federal ministers.
Technically Minister of State(except those holding independent charge) reports to the federal Minister of his department. He is a second rung leader in the departments hierarchy after the federal Minster.
