Mian Nawaz Sharif has wiped the slate clean with his initiative to get two major political parties to sign the CoD. The Charter binds the signatories to politics of principles, support the government in power, refrain from destabilising a government, forges commitment to a free judiciary and commitment to a free media, so on and so forth. Mr. Sharif has proved his commitment by supporting the PPP government for a whole year. This was a first in Pakistan politics. Nawaz Sharif can only be faulted if he fails in any of the commitments he is a signatory to, and not for anything he might have done prior to signing the CoD. This actually is his NRO. -KHURSHID ANWER, Lahore, via e-mail, March 16.
