Prime Miniser Yousuf Raza Gilani on Friday said that certain quarters were undermining the cause of Seraki province. Gilani,who arrived here on a three-day visit, was talking to newsmen at the airport. He said, on the contrary, the same elements were trying to create those provinces, which had never been in demand. He refused to comment on Pakistan Muslim League-Nawaz (PML-N) leader Chaudhry Nisar Ali Khan’s allegations of horse-trading in Senate elections. He also thanked the voters for electing his son Ali Musa Gilani in the by-polls.
