Banerjee's metamorphosis from a rabble-rouser to a pro-development politician was one of the issues she was queried on.

'How did this transition occur from the Mamata Banerjee whom we had seen gheraoing places and conducting aggressive movement to one with a smiling face and so much emotion and a touching attitude?' asked Patton MD and past president of Indian Chamber of Commerce Sanjay Budhia.

'I was always smiling. Your eyes were not open,' Banerjee replied.

Banerjee said the railways have already identified a land bank of 11,200 acres for commercial utilisation. 'I am impatient. I cannot wait. Let us start work immediately.'

Replying to one of the queries, she spellt out her priorities if her party came to power in the state: 'There is no land use map. We will do it immediately. There must be a landmap.'

'There will be no political pollution or collusion. We want industry. I can assure you won't be deprived.'

The minister ruled out any forcible acquisition of land, and said if such a problem emerged, she would go for another option.

Referring to the Singur episode where Tata Motors had to abort its plan to set up the Nano plant, she said the aggressive attitude in some quarters led to the disaster.

On the railways' philosophy under her leadership, Banerjee said: 'Our first eye comprising the railway board is for running the railway operations. The second eye is for commercial utilisation of railway land. The third eye is for balancing'.
