Penang BN chief Teng Chang Yeow will not yield to Penang Chief Minister Lim Guan Eng's threats to sue the former over allegations surrounding a Penang Development Corporation (PDC) deal.

Lim had imposed a 48 hour deadline on Teng to show proof of his allegations that the PDC rejected a deal in 2013 that would have guaranteed profits for the state-owned firm. The deadline expires tomorrow.

At a press conference today, Teng said that he had the proof and that Lim ought to be patient.
