New Delhi: Delhi CM Arvind Kejriwal has written a letter to PM Narendra Modi over not being allowed to attend the World Cities Summit to be held in Singapore. He expressed displeasure through the letter, terming the Centre's behaviour as wrong. In fact, the Singapore government has invited the Delhi government for the World Cities Summit. Joining the summit, Kejriwal was to present the Delhi model in Singapore. But they have not yet received permission from the Central Government to go there. For almost a month, Kejriwal's file has been lying with the central government, but there has been no response. Now Kejriwal has written a letter to Prime Minister Modi asking him to be allowed to go to Singapore as soon as possible so that he can increase India's value on foreign soil. In his letter, Arvind Kejriwal wrote that the Delhi model has to be presented to many big leaders from all over the world in Singapore. Today the whole world wants to know about the Delhi model. This invitation from there is a matter of pride and honour for the country, but it is against the interest of the country to stop a Chief Minister from going to such an important forum.
