Northamptonshire-based Formula One team Mercedes have announced that Team Principal Ross Brawn is to step down.
As we reported last month, speculation had been mounting that Brawn was considering his position and it's now been revealed that he will leave at the end of the year.
Executive directors Toto Wolff and Paddy Lowe will now lead the team heading into the 2014 season, with Lewis Hamilton and Nico Rosberg confirmed as the team's drivers.
Speaking to the team's official website, Brawn said that the time was right to call time on his association with Mercedes:
"The most important consideration in my decision to step down from the role as Team Principal was to ensure that the timing was right for the team in order to ensure its future success.
"The succession planning process that we have implemented during this year means we are now ready to conduct the transition from my current responsibilities to a new leadership team composed of Toto (Wolff) and Paddy (Lowe).
“Mercedes-Benz has invested significantly in both the personnel and infrastructure at Brackley and Brixworth.
"Thanks to the one-team approach we have implemented between the two facilities, the team is uniquely positioned to succeed in 2014 and I am proud to have helped lay the foundations for that success."
The British Grand Prix is taking place today at Silverstone in Northamptonshire. Last year 297,000 people attended despite torrential rain which almost saw the event cancelled.
Top drivers from around the world will be competing in the Grand Prix which has been held since 1950.
The race includes 52 laps around the circuit - a total of 5,891km. The lap record for the circuit has stood since 2010 when Fernando Alonso set a time of 1:30.874.
No through traffic allowed due to F1 Grand Prix at Silverstone on A43 in both directions between A422 (Brackley) and A5 (Towcester).
Only race spectators will be able to use this section of the A43. A one way system will be in place for traffic heading to Silverstone in the morning and away from Silverstone in the afternoon.
Diversion - Between M1 J15 using A508 and A422 via Old Stratford and A421 between Buckingham and the A43 just South of Brackley.
The wretched British summer wreaked havoc over Silverstone as first practice for this weekend's grand prix was almost a total washout. As rain poured the teams decided to remain dry in their garages despite the tens of thousands of fans packed around the Northamptonshire circuit.
The only action during the opening 75 minutes was an installation lap apiece from all the drivers bar Lotus' Kimi Raikkonen and Jean-Eric Vergne in his Toro Rosso.
It was Vergne's team-mate Daniel Ricciardo who ultimately took the lead. Only 11 drivers bothered to post a time.
Around 100,000 people are expected to descend on Silverstone in Northamptonshire this weekend for the British Grand Prix. Practice gets underway today with qualifying tomorrow and the race on Sunday.
Three local teams are taking part, Red Bull from Milton Keynes, Mercedes from nearby Brackley and Force India, which based just outside the circuit.
Organisers at Silverstone say they are making contingency plans ahead of the Formula 1 Grand Prix in June to prevent a repeat of last year's event which was marred by the weather.
Some fans were told to stay away from the circuit in Northamptonshire while others faced huge traffic jams and muddy campsites because of flooding.
Work is now being done to improve drainage at the site with more transport options for race-goers.
Formula One fans who missed a day of action at this year's British Grand Prix have until Friday to claim a refund from Silverstone.
Weeks of heavy rain flooded campsites and car parks at the Northamptonshire circuit last month.
As a result organisers asked people to stay away on some of the qualifying days.
Between 20,000 and 30,000 fans were affected, though 297,000 people still attended despite the awful conditions.
Anyone wanting a refund should visit the Silverstone website.
