Two weeks ago, Gayle resigned the post he held since last August after being reportedly unhappy with the WICB's selection policy and has openly criticised the body, specifically over its experimenting with the squad for the home series against Australia in May and June.
Word of Gayle's change of heart has been communicated to the WICB, with Gayle explaining that he reconsidered his decision after meaningful discussions with board president Julian Hunte on the issues raised in the resignation letter.
According to the source, Gayle revealed that his decision was also influenced following frank exchanges with several of his teammates and some dedicated supporters of West Indies cricket.
The hard-hitting lefthander was handed the captaincy of the WI team for a limited overs tour of England and Ireland last year, but has had mixed results during his tenure.
He led the West Indies in the away series against South Africa, which the home team won 2-1, and retained the top post for the home series against Sri Lanka, which ended in a 1-1 draw in April.
The West Indies will play in a triseries involving Bermuda and Canada later this month, as well as the ICC Champions Trophy in Pakistan in September.
