Lahore (Staff Report): The National Accountability Bureau (NAB) has written a letter to the Interior Ministry asking to put names of former prime minister Nawaz Sharif, his daughter Maryam Nawaz and her husband Capt (retd) Safdar on the Exit Control List (ECL).

Earlier, NAB Chairman Justice (retd) Javed Iqbal on Wednesday approved to file two supplementary references against Sharif family in Al-Azizia Steel Mills, Flagship Investment and Hill Metal Establishment cases.

Former Prime Minister Nawaz Sharif, his sons Hasan and Hussain are accused in the two references.

According to sources, the NAB will submit the supplementary reference to an accountability court, hearing main corruption references against Sharif family.

The anti-graft watchdog has also filed a supplementary reference in January regarding the London properties case.

The NAB filed three corruption references against the Sharif family in September last year in light of the Supreme Court's July 28 verdict in the Panama Papers case.
