Try this
  
public class Parser_New{
    public Blob myfile{get;set;}
    public Parser_New(){
        reports = new fromJSON(); 
    }
    
    public fromJSON reports {get;set;}
    
    public void doUpload() {
        System.debug('myfile'+myfile.toString());
        reports =  (fromJSON) System.JSON.deserialize(myfile.toString(), fromJSON.class);
		
		
		List<cls_record> rec = reports.leaddata.record ; 
		
		
		List<Lead> leadList = new List<Lead>();
		for(cls_record c :rec){
			leadList.add( new Lead( FirstName =c.FirstName ,LastName = c.LastName , Phone =c.Phone , Email =c.Email) ;
		}
		insert leadList;
        
    }
    
    public class fromJSON{
        public cls_leaddata leaddata{get;set;}
    }
    public class cls_leaddata {
        public cls_record[] record{get;set;}
    }
    public  class cls_record {
        public String FirstName{get;set;}	//Veera
