The division has a market value of £269 million.
The sale is the latest in a string of recent disposals by the insurance giant. Over the last six months it has sold its US business for £1.1 billion, Dutch firm Delta Lloyd for £671 million and has agreed to sell its 49% stake in a Malaysian joint venture for £152 million.
The sales are part of a restructure kicked off by chairman John McFarlane while he was in temporary charge after the departure of previous chief executive Andrew Moss.
The plans, which have been taken on by new chief executive Mark Wilson (pictured), will also see the company cut costs by £400 million
The sale of Aviva Sigorta will mean the company has completed 90% of its planned sales, with the remaining focus of its restructure now on cost cutting, according to the Telegraph.
