Yes. Basically, GM all but pulled out of the European market by selling Opel/Vauxhall.
That meant it pulled out of the UK and Ireland.
GM also pulled out of India because of difficult market conditions* there
So, no UK or Ireland, no India and Japan's would be a tough market to break.
Not really worth the effort for a low volume BEV.
It leaves Nissan rubbing its hands, since that means no big competitor for the new Nissan Leaf in the UK.
Now Nissan also owns Mitsubishi, so it'll almost certainly have the two biggest-selling plug-ins in the UK in 2018. Nissan's already selling 3-4k Leafs per month in Japan and has high demand in Europe.
And there are people who keep insisting that Nissan should drop CHAdeMO in Europe because it's dead. 8-|
* Difficult market conditions = >_100%_ whopping import tariffs on cars. Taxes are 15% or 25% on domestic luxury cars. This is why I have repeatedly noted that I'm not interested in the Jaguar iPace: Jaguar-Landrover is owned by the Indian company Tata Motors.
