Some figures among F1’s large German contingent are reportedly unhappy about a gaffe by organisers of the Canadian grand prix.
The current world champion and championship leader is German, as are several other drivers, and there is a German team, race and engine supplier in F1.
"But the German flag is apparently unknown in Montreal," read a report by the German sports news agency SID.
The report said the supposedly German flags above the pit garages, and also on banners on the way into the Circuit Gilles Villeneuve, are in fact Belgian.
The German and Belgian flags are both black, red and yellow tricolour, but the Belgian colours are arranged vertically rather than horizontally and in a different order.
