Mohanish,
Yes, the above statement is correct. Leadership is a part of management but not all of it. Under management, all the functions are included such as  planning, organising, staffing and directing.​ A manager has to perform all these functions besides peforming the duties of a leader. An organisation may or may not hire a leader as a manager has to perform the functions of the leader also. So, we can say that management is incomplete without leadership.On the contrary, leadership is a part of management as a leader has to follow or attain the objectives framed by the management. 

The following points highlight the difference between a manager and a leader.

Basis of Difference	Manager	Leader
Existence	A manager can exists only in a formal organisation.	A leader can exists in formal as well as informal organisation.
Objective	A manger focuses towards influencing the behaviour of employees towards achievement of the goals of the organisation.	A leader focuses towards the satisfaction of the individual and group goals of his followers.
Power and Authority	A manager holds formal authority and can exercise power and control to influence the behaviour of the employees.	A leader does not command formal authority and can only influence the behaviour of the followers through such means as trust and faith.
Interrelationship	A manager can be a leader as well.	A leader may not be a manager.
Functional Spread	The functions of the manager are widespread and include planning, organising, staffing and directing.	Functions of a leader are limited to directing.
