Nigerian opposition presidential candidate Atiku Abubakar urged the central bank on Saturday to extend a Jan. 31 deadline to phase out old high-value banknotes, a measure many Nigerians fear will disrupt business in the cash-reliant economy. Nigerians have to turn in 1,000 ($2.17), 500 and 200 naira notes by Tuesday when they cease to be legal tender. The central bank started releasing newly designed notes last month but many Nigerians say they are not yet available in banks.
