Lanark's Colin McRae maintained his lead in the Rally of Portugal behind the wheel of his Ford Focus World Rally Car oblivious to the wild rumours which suggested he was about to launch a career change and race in Formula One.

As the 30-year-old set a blistering pace through the narrow roads which criss-cross the Iberian countryside, dad Jimmy admitted he was

surprised by the reports which rattled the motorsport world yesterday morning.

Waiting for his former world rally champion son at the

service halt in Mortagau in the early afternoon, McRae Sr said: ''It's all news to me. I haven't a clue what all this nonsense is about. I spoke to him less than an hour ago and there's certainly no plans for Colin to undergo a career change at the moment.

''He's the fastest rally driver in the world driving for the biggest manufacturer in motorsport with the best car in the championship. Why, tell me, would he want to go into Formula One? I think you'll find something's been taken out of context.''

The facts behind the broohaha are simple and confirm the suspicions that someone has taken two-plus-two and come up with five.

Recently father and son McRae, Ford's head of motorsport in Europe, Martin Whitaker, and Stewart Grand Prix top men Jackie and Paul entered into a casual conversation over coffee. And, remembering that in all this the common denominator is Ford, who also supply the V10 engines to Stewart Grand Prix, Paul Stewart takes up the story.

''Sure we all talked,'' he explained yesterday, ''but it was to set up a project where we would allow our grand prix drivers, Rubens Barrichello and Johnny Herbert, to experience a Ford Focus World Rally Car and in exchange we'd let Colin have a go in our F1 car.

''It's as simple as that but someone's got hold of what they though was a good story and turned it into a better one.''

Whitaker, while happy to lap up the publicity the story generated for Ford, was keen to re-focus attention on the job McRae is being paid #6.5m to do.

''No-one doubts Colin's streets ahead of F1 drivers in terms of being a complete

driver,'' he said, ''but we're paying him to win the world rally championship and that's exactly what we want him to do.''

McRae seems to be on his way to collecting a second

successive victory in the Ford, but while he takes a 33sec advantage into the closing four stages today, he knows it would have been more if the final two stages had not been cancelled due to fears for spectator

safety.

''We'd had to back off on what turned out to be the last stage because our tyres were worn,'' McRae said, ''and we were all set to give it a real blast through the final two and eke out some more time.

''But there was no way through the vast number of people who weren't only lining the route, they were blocking it completely.''

Tucked in behind the Scot is Spaniard Carlos Sainz who McRae pipped here last year by just 2.1 seconds. The closest

finish in world rallying. There was further good news for the McRae family. Younger brother Alister, in a stunning thirteenth position overall, still leads the two-wheel-drive, two-litre class by 32.5 seconds from his Hyundai team-mate Kenneth Eriksson.
