Colin Craig says he has received an apology from the Taxpayers' Union executive director Jordan Williams over false allegations.
He says Williams has admitted making false allegations, unreservedly apologised to him and his family and made a payment.
Craig, a former leader of the Conservative Party, released the full apology and details of a payment made to him via a media statement this morning.
A screenshot of a typed apology shows the executive director of the Taxpayers' Union, apologising for his "untrue statements'' made against Craig.
"I wish to apologise publicly for the untrue statements I have made about Mr Craig."
