* Unions say may call off strike on Wednesday
* Presidency says will work on new minimum wage
Nigeria's unions moderated their threat of a three-day strike after the intervention of President Goodluck Jonathan late on Tuesday, saying they would still stage a stoppage but may call off the action later on Wednesday.
The Nigeria Labour Congress (NLC) and the Trade Union Congress (TUC) had threatened a three-day warning strike from Wednesday followed by an indefinite stoppage to press demands for an increase to the monthly minimum wage.
Jonathan cut short a visit to the commercial hub Lagos on Tuesday to lead emergency talks late into the evening in a bid to persuade the unions to drop their threat.
"We have heard the message of Mr President ... We will meet tomorrow by 3 pm (1400 GMT) and we will announce the outcome of our meeting, whether or not to call off the strike," acting NLC president Promise Adewusi told reporters after the meeting.
