Leader of the opposition and Bharatiya Janata Party chief L K Advani on Wednesday said the United Progressive Alliance government is driven by the agenda of 'political vendetta'.

He also asserted that the UPA's communist allies would prove to be a 'liability' in achieving any good.

The senior BJP leader was addressing the Confederation of Indian Industry's Annual Session and National Conference on achieving 'Inclusive and Double Digit Growth'.

"The National Democratic Alliance is being constantly run down. Such illiberalism in our political culture does not augur well for either our democracy or for our economy," Advani said.

"What I am particularly concerned about is that this political illiberalism is leading the government to a policy of vindictiveness," he added.

He pointed out the 'politically-motivated' Central Bureau of Investigation probe into the defence deals and the disinvestment of Centaur hotels in Mumbai are examples of the 'vindictiveness'.

On the UPA completing one year in power, Advani said the only glue that holds the 'strange coalition together is anti-BJPism'.
