Morley came to know about Motorola being acquired by Lenovo about 30 minutes prior to the deal.
Motorola UK managing director Andrew Morley is departing from the future Lenovo-owned mobile phone firm after seven years of service.
He took charge as Motorola UK’s vice president of international marketing in 2010, and was responsible for its ‘Life Empowered’ advertising campaign.
Morley was cited by the Guardian as saying it is the right time to move.
"It is very difficult to commit to another three years at the company now that it is in the hands of Lenovo," Morley added.
"Google was a great employer, and many people stuck around at Motorola because of Google, but now that incentive has gone."
Morley’s exit comes three months after the Chinese PC maker agreed to snap up Google’s struggling US- smartphone unit for $2.91bn, two years upon being acquired by Google for $12.5bn.
Claimed to be China’s largest-ever tech deal, the approval pending acquisition would bolster the Chinese PC maker’s position in the global smartphone market, while boosting its smartphone business in North America and Latin America, and build up its grip in Western Europe.
