Correction:

• Just executive President no Prime Minister directly form people. (Like in US)

It is not true. President is not directly elected from people in USA. It is from electoral college. Even though president gets more popular votes (individual votes from people) there is a chance that president  will lose the election.

Example: Al Gore got more vote than Bush in 2000 election. Nixon got more vote than Kennedy in 1960. But, Bush and Kennedy got more elctoral votes and won the presidency.
