Traveller Days are local initiatives held by prisons: they are dependent on establishments having recognised groups of prisoners from Traveller background. The Prison Service considers it best practice for establishment to hold such events.
Information is not held centrally on events such as Traveller Days held in prisons. To collect the information requested would require contacting all 125 public sector prisons in England and Wales individually and for each establishment to conduct a manual check of their local records. It is not therefore possible to provide figures for the number of such events in the last three years or their costs.
