Lahore - Pakistan Muslim League-Nawaz President Nawaz Sharif has said that his party will stand by the court if Prime Minister Yousuf Raza Gilani does not write letter to the Swiss authorities. “PM Gilani has no option but to write to Swiss authorities as mere apology won’t do,” he told a private TV channel. Nawaz said the implementation of 20th amendment will ensure transparent elections. The PML-N president said his party did not take U-turn on the memo issue and it sticks to its guns over the issue.
