Different scenario.
Mitsubishi has been in trouble for a number of years and were badly hit by a scandal involving falsifying economy figures in their home market. Nissan bought a controlling interest in them in 2016. Concentrating on their South East markets, where they are stronger, should help rebuild the company.
Nissan themselves are suffering from declining demand and heavy discounting (which has backfired for them) in the US market, and, as with Mitsubishi, big falls in profits. Nissan are also retracting in Europe - with plans to close their Spanish plant, etc.
Mitsubishi's UK importer, which is a separate company to the manufacturer, has already approached other manufacturers to replace Mitsubishi (certainly at least one Chinese company) regarding distribution of vehicles in the UK.
By the way, the Outlander PHEV's multi mode transmission was designed and made by GKN Automotive - a British mulinational.
