"The Saudi government and Mr Hariri, the guarantors of the exile undertaking the PML chief had signed before being released from jail and sent to Saudi Arabia in Dec 2000, had on Saturday advised him at a press conference in Islamabad not to violate the undertaking. Nawaz Sharif rejected their advice in a tit-for-tat press conference at London on the same day, saying that Mr Hariri had not kept his promise to revise the exile period down to five years _ a promise which he said he had obtained from Mr Hariri before signing the undertaking."
