UK region overlay on map

Can Google Maps display UK counties?

Google Maps already shows the boundaries of England, Wales, Scotland and Northern Ireland, but it’d be more useful to me to see the county boundaries.
 

How do I get a map overlay on Google Maps?

Maps are created with one layer, but you can have up to 10.

1. On your computer, sign in to My Maps.
2. Open or create a map. You’ll see your layers in the box on the left.
3. Make the changes you want. Add a layer: Click Add layer. Then click the title and add a name. Delete a layer: Next to the layer title, click More.
