Former Punjab chief minister Amarinder Singh has postponed his trip to Lahore where he was to release his book 'The Last Sunset: Rise and Fall of the Lahore Durbar'.

'In the wake of the current situation prevailing in Pakistan, I have deferred my trip for another few weeks. This decision has been taken on the advice of my friends and very soon I will announce the new date of my visit,' Amarinder Singh told IANS here Thursday.

Amarinder Singh, who released his book here March 9, was going to Pakistan on a 10-day visit through Attari-Wagah border March 25.

A 20-member delegation, comprising senior politicians and journalists, was also to accompany him to Pakistan.

The book is about the heroic Sikh king, Maharaja Ranjit Singh.

At the release of the book here, Amarinder Singh said he had spent over five years researching and made various trips to Britain and Pakistan to consult documents in museums and archives there.
