Nissan also recently scrapped plans to build its new X-Trail SUV in Britain amid the uncertainty surrounding Brexit, saying it had taken the decision to optimise its investments by building the next generation model in Japan.
Infiniti will continue selling cars in Russian Federation and eastern Europe, it said.
The Nissan division added that it aimed to transform Infiniti into a "top challenger brand" in the premium sector of the world vehicle marketplace.
Infiniti announced Tuesday that as part of a "restructuring plan" that will favor the large United States and China markets, the automaker will cease operations in Western Europe.
Nissan to withdraw luxury Infiniti brand in Western Europe in 2020
Infiniti cars will no longer be sold in Western Europe from 2020 after Nissan bosses chose to pull the premium brand from the market. Infiniti wants to go fully electric by 2021, and thus won't sell any diesel-engined cars from that date.
"In the coming weeks Unite will be working closely with Nissan to protect jobs and ensure that redeployment is carried out in an open and transparent way".
The Infiniti brand has struggled to make a mark in Western Europe- past year sales halved to 5,800. "This is all part of Infiniti's vision to become a top challenger in the premium segment", the company said.
In today's statement Infiniti said that the business was now working to "find alternative opportunities for any employees affected by its restructure, consulting with employee representatives where necessary and identifying opportunities for transition and training support where appropriate". There are 55 Infiniti retail stores in western Europe.
Infiniti has 51 employees in its western Europe operations.
