What's different between Leader & Manager?

A Leader takes the lead in the implementation of the policies and guidelines conceptualized by the Manager. However, both roles are interrelated to each other because it can be performed by both. 

The main difference between leaders and managers is that leaders have people follow them while managers have people who work for them.

Leader will give leads only or rather command Manager get along with peers to execute to achieve it 

Without followers a Leader is none, leader leads their followers!. Their must be a group or a class of people who follows the leader with their individual interest on particular field.

Managers instruct their respective teams for any specific goals or objectives generally made by any organisation or company.

 It is not necessary that a Manager can be a Leader but a Leader can become a good Manager.
