Delhi Deputy Chief Minister Manish Sisodia on Wednesday asked if the house tax of BJP leader Vijay Goel's mansion could be waived off, then why not for Delhi's commoners.Sisodia said the municipal corporations in August last year decided to exempt tax on Goel's 'haveli' (mansion)."If the House (Muncipal Corporation of Delhi) can waive off tax of a BJP leader's haveli, then why one needs to go to Parliament to do the same for common people?" Sisodia asked."Why the rules are different for the common people and the politicians?"He added that if voted to power in the civic elections, the Aam Aadmi Party will use the same rules and powers to exempt house tax for common citizens, which the Bharatiya Janata Party-ruled corporation used for its leader.
