MOSCOW, Nov 4 (Reuters) - The Russian government could allow French group Renault (RENA.PA) to buy control of AvtoVAZ (AVAZ.MM) as part of a plan to save the ailing carmaker, a Russian government source told Reuters on Wednesday.

The move could make Renault Russia's top foreign partner in the car industry after the decision by General Motors not to sell Opel to a Russian-Canadian group dealt a blow to Kremlin's plans to modernise the auto sector. [ID:nL4519517]

"At the end of the day the government will search for a strategic investor -- and it will likely be Renault," said the source, who asked not to be identified. "They (Renault) are ready to increase their stake and are looking at the option of increasing to a controlling stake," the source said.

Renault currently has a 25 percent stake in AvtoVAZ, Russia's largest carmaker which has been hammered by tumbling car sales in the worst Russian recession since the mid 1990s. The government and brokerage Troika Dialog own 25 percent each while the rest is freely floated.

A Renault spokeswoman said the company already viewed itself as a strategic partner for AvtoVAZ, given its 25 percent. "We maintain this participation. Our contribution to restructuring will be through technology, equipment, know-how and platforms."

AvtoVAZ wants to cut a quarter of its workforce in Togliatti -- a city on the river Volga that only exists for the plant's workers -- to cope with plummeting sales and heavy debts.

The Kremlin has been reluctant to allow the firm to proceed with job cuts fearing they could lead to mass unrest that would hit support for the government of Prime Minister Vladimir Putin.

PRESSURE ON RENAULT TO EASE

Putin said on Wednesday he was surprised by GM's decision not to sell Opel after months of negotiations with a consortium of Magna (MGa.TO) and Sberbank (SBER03.MM), and hinted the battle was not over [ID:nL4159263]
