Viva Energy REIT's major shareholder, fuels supplier Viva Energy, is divesting its entire remaining stake in the $2.2 billion petrol station property trust it spun off and floated four years ago.

In an after-market announcement on Thursday, Viva Energy, which holds a 35.5 per cent stake in the property trust, said it is selling 5 per cent to listed fund manager Charter Hall and another 5 per cent to the Charter Hall Long WALE REIT.
