Williams F1 has renewed and 'upgraded' its current sponsorship agreement with Randstad, it has been announced following the launch of the new FW35 today at Barcelona's Circuit de Catalunya.

The global recruitment company has backed the team since 2005 and as in previous seasons Randstad branding will appear prominently on the engine cover and cockpit surround of the car, whilst also appearing on the front and back of all the team's apparel. In addition Randstad branding will also appear on the drivers' caps.

"Randstad is one of our longest standing partners and very much part of the Williams F1 Team family," commented Sir Frank Williams, Williams F1 team principal. "Strong partners are fundamental to success in F1 and together we are looking forward to the next two seasons ahead."

Meanwhile, the Grove-based outfit has also confirmed a new 'partnership', with Experian, the global information services company, inking a 'multi-year' agreement.

As sponsors, the Experian logo will be visible on the chassis side and front wing of the FW35, and will appear on each driver's overalls, their respective helmets, and team personnel's kit.

"We're delighted to welcome a global company of Experian's stature to our stable of partners in what will be a rewarding relationship for both parties," Sir Frank added.

"We're working hard towards a strong season this year and the support of a company like Experian will prove pivotal in achieving more success for Williams in 2013."
