The United Auto Workers union is close to completing a tentative agreement on a new contract with General Motors, two days after the union clinched a tentative deal with Ford Motor.

The two sides negotiated throughout Thursday night and into Friday morning, and reconvened in the early afternoon in a push to secure a deal, people with knowledge of the talks said. GM presented an offer overnight that is similar to the tentative agreement that the union struck with Ford on Wednesday, the people said.
