As if Saab didn't have enough on its plate, what with the tortuously slow will-they/won't-they European Investment Bank (EIB) deliberations, it gets hit by a broadside from the Swedish embassy in Beijing.

A leaked report by the embassy apparently detailing its opinions on potential Chinese investor Hawtai appears to contain some "subjective" views that have not gone down entirely well back home.

A reliable Beijing source told just-auto today (6 May) Swedish ambassador to China Lars Freden had said it was the Embassy's job to report to the ministry - presumably the foreign ministry in Stockholm "what we know and what we don't know."

Known unknowns? Whatever the content - and its precise detail remains unclear - the leak has not gone down a storm in Trollhattan - although Saab is putting a brave face on it.

"It is unfortunate," a Saab spokeswoman told just-auto with admirable sang froid, adding for good measure: "Who knows how that happens, but things happen."

With equal restraint Saab drily noted it was engaged in "a dialogue with the embassy in Beijing to clear up if they have concerns," an understatement if there ever was one.

While not overly damaging, the leak is yet another twist in the Saab saga that continues to hog the front pages in Sweden.

The cat seems to be well and truly among the Swedish pigeons however, with one further source in Beijing noting to just-auto that deliberations are now taking place in Stockholm as to whether the infamous Beijing report should be made public.

Meanwhile, the EIB plods ever more slowly towards its verdict on the multiple financial strands of any restart deal that - to date - there appear to be increasing layers of complexity every day - could, could, eventually see Saab turn the start key once more.

It's as if just when Saab thinks it's plugged one leak in the sieve, another hole springs up. It never rains but it pours.
