Problems these days faced by our nation are: (a) Food shortages and the rising prices. (b) Energy shortage and its rising prices. (c) Bomb blasts in cities and the law and order situation in FATA. The PP government is single-handedly fighting these problems. PML (N) has sidelined itself from the scene. Mian Nawaz Sharif should join the government at the centre and work hand in hand with PPP to avert the grave situation that is bringing the factories to a close and the economy to a collapse. He should be rest assured the judiciary problem will be settled eventually. -IJAZ H. MIAN, Lahore, via e-mail, July 14.
