ISLAMABAD: The Swiss authorities, who were contacted by the Pakistan Muslim League-Nawaz (PML-N) government to reopen the pending graft cases against former president Asif Ali Zardari, said on Tuesday that the time limit to do so has passed.

In April 2010, Swiss attorney general Daniel Zappelli had stated that since Zardari as President enjoyed immunity under international law, Swiss courts could not entertain any request to reopen the cases against him.

In their latest response, the Swiss authorities reiterated that the time to re-open graft cases worth $ 60 million against Zardari had passed.—INP
