Kolkata, Jan 31 (IANS) Kolkata Book Fair authorities Tuesday said they had apologised to former Pakistani cricketer and politician Imran Khan for switching off power supply during a talk by him a day earlier as the event had crossed the scheduled time.

‘We are ashamed for yesterday’s incident. What happened was shameful. We had also apologised to Imran Khan. He had said that it was a small incident and was not at all an issue for him,’ general secretary of the Publishers’ and Booksellers’ Guild Tridib Chattopadhaya said.

However, he evaded numerous queries on whether the blackout was intentional or an electricity failure.

‘I don’t want any controversy on what I said yesterday and what I am saying today. You can interpret anything… I will not say anything on the issue,’ said Chattopadhaya.

He had Monday said power supply was ‘intentionally’ switched off to stop the programme as it was continuing beyond the scheduled time.

The blackout lasted for some four-five minutes during the discussion programme ‘Captaining a nation’ where Imran Khan was the main speaker.
