How can I delete activities related to lead through salesforce apex code?

Hi pranav ,

you can try something like this

List<Lead> leadList = [SELECT Id FROM Lead ];

for(Task objTask:[Select Id, Subject, WhoId FROM Task WHERE WhoId IN: leadList )

{—-Delete related task here—–

—-or save it in list and delete at last —-

}

Hope it may Helps

Thanks
