Colin Craig's membership has been suspended from the Conservative Party following a decision by the just-appointed new board.
Board chairman John Stringer said he voted against the measure, but was overruled by a majority of the five member board.
The final decision about Craig's membership and who the new leader will be will be made at a later yet-to-be decided date, Stringer said.
Stringer said he had not spoken to Craig.
Stringer said the issue between Craig and his former press secretary Rachel MacGregor was "now a private matter".
