The Congress on Wednesday said that by laying the foundation stone of the Ken-Betwa River Linking Project, Prime Minister Narendra Modi will give another proof of the difference between his "talk and walk" on environment as it poses a serious threat to the Panna Tiger Reserve. Modi will lay the foundation stone of the project, the first such initiative under the national river interlinking policy, at Khajuraho in Madhya Pradesh on Wednesday. "Today the PM is giving one more evidence of the difference between his 'talk' and 'walk' on environment and forest matters. The Ken-Betwa river linking project for which he is laying the foundation stone today poses a serious threat to the biodiversity-rich Panna Tiger Reserve in Madhya Pradesh," Congress general secretary in-charge communications Jairam Ramesh said in a post on X. Panna is the most remarkable success story of revival as by early 2009 its tiger population had been completely wiped out. Thanks to the tiger reintroduction program
