On the JLR cuts, Mr Quinn said: "With record levels of new investment and models set to come on stream in its United Kingdom factories, we look for Jaguar Land Rover to continue to be a global success and the jewel in Britain's manufacturing crown".
A spokesman for the union Unite said: "Unite is not aware of any further job losses to those already announced and planned for early in the new year at Jaguar Land Rover, Unite also expects ongoing transparency regarding the hard current climate the automotive sector is operating in the United Kingdom and its impact with the company". The move comes after the company shed 1,500 jobs in 2018.
The company's move follows plans announced past year to reduce white-collar jobs across the company's global business.
The firm has also complained about uncertainty caused by Brexit. "This is in addition to the 1,500 people who left the company during 2018", the company said in a statement.

"Britain's vehicle workers have been caught in the crosshairs of the government's botched handling of Brexit, mounting economic uncertainty and ministers' demonisation of diesel, which along with the threat of a no deal Brexit, is damaging consumer confidence", Unite national officer Des Quinn said.
If, as expected, the United Kingdom bears the brunt, or the entirety, of JLR's global cost-cutting, JLR may well say it tried to warn us.
Global automakers must adjust to sweeping change expected from a move toward battery-powered and autonomous vehicles, and toward providing transportation as a service through ride-hailing and car-sharing smartphone apps.
In Jaguar Land Rover's case there are some additional factors beyond the slowdown in the Chinese economy and cautious consumer spending.
