Manvendra has also been removed from the membership of the BJP National Executive following reports that he was campaigning against the party's official candidate in Barmer.
Manvendra, an MLA from Shiv in the Barmer LS constituency, campaigned for his father.
Jaswant had termed the action against his son as "revenge".
"This kind of step has been taken with the intention of taking revenge. This is condemnable because he (Manavendra) is here for so many days and I never used to meet him fearing what the party will think about it. Injustice has been done surely", he had said after his son was suspended in April.
