 Complete the following phrase:  With the German Grand Prix being cancelled after safety concerns and complaints about the general quality of the AVUS track in Berlin, there was a month between the British and Portuguese GPs and at the challenging and dangerous Boavista street circuit in Porto Stirling Moss made his F1 comeback after being out of action since the disastrous Belgian GP in June. The only other change of note was that local hero Mario Cabral was found a drive in the second Scuderia Centro Sud Cooper-Maserati. In practice Henry Taylor crashed his BRP Cooper heavily and injured his arm while Jim Clark smashed up his Lotus in a rare crash. Despite the accident pole position went to Team Lotus driver John Surtees, who edged out Dan Gurneys BRM by a few hundredths of a second. Jack Brabham was third quickest in his normally-domit works Cooper. Moss put his Walker Lotus on the second row alongside Graham Hills BRM. Brabham took the lead at the start but Gurney quickly found a way ahead and then Brabham went wide at one corner and dropped to sixth place. Moss emerged second with Surtees and Phil Hill in his Ferrari fighting with him. After 10 laps Gurney dropped back with an oil leak and so Surtees took the lead with Moss in pursuit but he had to stop because of spark plug problems and dropped to the back of the field. He was later disqualified for driving against the direction of the race while trying to get going after a spin. Brabham had a lively fight with P Hill until the American crashed and this became the lead on lap 36 when Surtees went off because oil had leaked onto his pedals. Bruce McLaren came through to finish second to give Cooper another 12 result with Clark finishing third in his cobbled-together Lotus. Brabhams victory meant that he clinched the World Championship with two races remaining. But this was to be the last Portuguese Grand Prix for 24 years  the race would not return until
