British F1 star with 'unfinished business' after being loaned to rival team - On This Day

On this day 26 years ago, Williams confirmed that Jenson Button would be loaned to Benetton for two seasons, a decision that reshaped the career of one of Britain's brightest young talents.

The announcement on 17 August 2000 brought an abrupt pause to Button's breakthrough year at Williams. At just 20 years old, the Englishman had been making a strong impression in his debut season, scoring 12 points to sit eighth in the drivers' championship.

A stunning third on the grid at Spa-Francorchamps and a best finish of fourth in Germany had marked him out as a serious prospect, but none of it was enough to keep his seat.

The reason was simple: Williams had a long-standing agreement with Juan Pablo Montoya, the Colombian who had stormed to the 1999 CART title and the 2000 Indianapolis 500.

Once Montoya was ready to cross the Atlantic, Button was always the driver who would have to make way alongside Ralf Schumacher.

Rather than releasing Button outright, Frank Williams opted to retain his contractual rights, sending him to Benetton on a two-year loan with the option of recalling him from 2003. It was a shrewd piece of business, allowing Williams to develop a future asset while fulfilling their commitment to Montoya.

Button, for his part, expressed gratitude rather than frustration.

"I will always be eternally grateful to Frank Williams and Patrick Head for giving me my great opportunity in Formula One," he said. "I have some unfinished business at Williams."

That unfinished business, as it turned out, was never completed in the way he imagined. Although Button twice came close to rejoining Williams in subsequent years, contractual disputes and shifting allegiances meant he never raced for the Grove-based team again.

Instead, his career took him through Benetton, Renault, BAR, Honda, Brawn GP and McLaren, culminating in 15 grand prix victories and the 2009 F1 drivers' championship.
