Union's Senedd slavery day vigil
Events are being held in Wales to mark a national day of memorial for the abolition of slavery.
Unison Wales black members group will stage a torchlight vigil at the Senedd in Cardiff from 1930 BST, and there will also be musical performances.
The union campaigned to make 23 August a day of memorial.
In Swansea the African Partnership Group hosts a commemoration event at the National Waterfront Museum (1800 - 2100 BST).
Unison black members group chair Kebba Manneh said: "It is important to remember the horrors of slavery and value the progress that has been made.
"Sadly, however, there is still much still to be achieved.
"There are still too many people in the modern world that suffer as a result of racism and slavery."
