The United Auto Workers (UAW) and the maker of Chrysler cars, Stellantis, have struck a tentative pay deal to end a six-week strike.

BBC News says the agreement, which still needs to be approved by union leaders and members, follows a similar deal that was struck with Ford last week.

The UAW has yet to reach a deal with General Motors, and is expanding action against the firm.

The agreement between the UAW and Stellantis will see wages for most workers rise by 25% over the next four-and-a-half-years, and the lowest-paid workers at Stellantis would see wages rise by more than 165% over the period of the agreement.

Stellantis workers will return to work while the deal is ratified, the union said.

President Joe Biden welcomed the agreement.

On October 28, the UAW said it would extend its strike against GM to the company's plant in Spring Hill, Tennessee.

Last week, GM said the strike action was expected to cost it about $200m per week.

The company also withdrew profit forecasts for the year saying it could not predict how quickly the stand-off would conclude.
