Prime Minister Yousuf Raza Gilani has extended an olive branch to his former ally PML-N after its chief Nawaz Sharif accused President Asif Ali Zardari of working against the interests of his party-led government in Punjab.

Gilani telephoned Sharif's brother and Punjab Chief Minister Shahbaz Sharif and gave him a categorical assurance that the federal government will not support any "undemocratic move" to "dislodge or undermine" the provincial government.
