Saab's plans to resume production may be stalled by the collapse of its funding deal with China's auto maker Hawtai.

Hawtai had pledged earlier this month to invest £150m euros into Spyker, Saab's parent.

However Spyker said the agreement had been terminated because Hawtai had been unable to secure shareholder approval.

Spyker said it would continue work to secure short and medium-term funding.
