The power showdown between the Senate and the Comptroller-General of the Nigerian Customs Service, NCS, Hameed Ali has taken a new twist.

The Customs Boss has written the Senate, notifying the lawmakers he will not appear before them on Wednesday as directed.‎ 

His letter was read on the floor of the Senate on Tuesday.

In his letter, he said he had to attend an NCS meeting.

The Senate had summoned Ali last Thursday over the planned clampdown on vehicles without duty payment.

In its resolution, the Senate said Mr. Ali must appear on Wednesday in appropriate Customs uniform which he claims he was not appointed to wear.
