M4 relief road: House sellers 'not had a viewing'
Millions of pounds worth of property and land along the preferred route for an M4 relief road around Newport is owned by the Welsh government, BBC Wales can reveal.
It has led to concerns this may have influenced its decision to choose the £1bn "black route".
The Wales Audit Office said the Auditor General had received a complaint.
There were three options and a row has broken out about a fourth which did not feature in a consultation.
John and Lauren Lawley bought their house at Knollbury near Magor, Monmouthshire in 2011 when they were told that plans for a relief road near their home would not go ahead.
But local uncertainty about the precise location of the new relief road has meant they cannot sell it even though they need to move.
Meanwhile, Economy Minister Edwina Hart said the issue with properties was inevitable when road developments happen.
