Prime Minister Narendra Modi will undertake a day-long tour of his Lok Sabha constituency tomorrow during which he is likely to launch important schemes relating to power and road sectors, inaugurate a trauma centre inside Banaras Hindu University premises, and address a public meeting. This will be the third visit of the Prime Minister to the ancient temple town after assuming office in May last year. The much-awaited tour comes nearly nine months after his previous trip on December 25 last year. However, his proposed tours were cancelled twice recently because of heavy rainfall on June 28 and on July 16.
