SIR Frank Williams is celebrating 50 years in Formula 1 and says he has no intention of stopping just yet.

The 77-year-old is marking the landmark at this weekend’s British Grand Prix at Silverstone.

Williams has enjoyed a successful career, which started in 1969 when he entered his Frank Williams Racing Cars team into the Formula 1

championship for the first time.

Selling up to Canadian businessman Walter Wolff, he joined forces with Patrick Head to set up a new team – Williams Grand Prix Engineering – in a factory in Didcot.

Since their first race in 1977, they have won nine constructors’ and seven drivers’ championships.

But a title has eluded them since 1997 and the team, which has been based in Grove for 23 years, have endured a difficult couple of seasons.

Drivers George Russell and Robert Kubica are yet to score a point in 2019, with the team bottom of the constructors’ championship.

Williams does not travel to many races anymore, but is present this weekend and has vowed he will be at the helm for a while longer yet.

“Fifty years in Formula 1. Honestly, I haven’t thought about it very much,” he said.

“I can’t say I’ve loved every minute of it, because moments have been very difficult – I’ve lost my wife, I’ve lost drivers. But Formula 1 has been very good to me.

“We’ve had great success, but there’s a well-known expression in F1: ‘You’re only as good as your last race.’

“We will keep on fighting – and I’m not going anywhere yet.”

Williams are the only team yet to score a point this season, but Kubica is hoping to deliver in tomorrow’s race.

“Silverstone is a big event for the team, as it is our home race,” he said.

“We hope for better performance and car improvements, but the track is very challenging.

“We will try our best and deliver what we can for our fans.”
