In a jolt to the Aam Aadmi Party (AAP), its leader from Doaba region H S Walia today joined the Shiromani Akali Dal along with his supporters ahead of the Shahkot bypoll scheduled to be held on May 28. Walia said he was joining the SAD due to its "pro-people" policies as well as the party's desire to take all sections of society with it. "I earlier joined AAP because it professed idealism. However I slowly realised that the party had become thoroughly corrupt and was not concerned about Punjabis and their problems. Moreover, AAP is being run from Delhi by Arvind Kejriwal who does not give any weightage to the local leadership," Walia alleged. Welcoming Walia into the party fold, SAD president Sukhbir Singh Badal said the youth leader had made a name for himself in a short period of time and would be an asset for the SAD in Jalandhar district. Walia would be duly adjusted in the party organisation and would be given important duties, he was quoted as saying in a release. The SAD president said the manner in which both the Congress and the AAP leaders were joining the SAD was indicative of the functioning of the Congress government as well as complete disillusionment with the Aam Aadmi Party. Badal said political leaders usually changed parties towards the fag end of any government's tenure, but presently leaders were "leaving the Congress in droves" because the party had "lost all appeal among the masses" after reneging on promises made to the people.
