( CNN ) -- After four months on the scrapheap Paddy Lowe will be back in the fast lane in June after his switch from McLaren to Formula One rival Mercedes was confirmed . Lowe was recruited by Mercedes in January only for McLaren to remove him from his role as technical director and insist he sees out his contract , which was set to expire at the end of the current season . It was originally thought Lowe would replace current Mercedes team principal Ross Brawn , but he will now work alongside his fellow Briton as `` executive director ( technical ) '' from June 3 . The Circuit : CNN 's F1 Interactive . `` I am excited to become part of a highly talented and capable technical organization , '' said Lowe , who follows 2008 world championship-winning driver Lewis Hamilton in swapping McLaren for Mercedes , in a statement . `` That is a challenge I am relishing . I have worked closely with Mercedes-Benz for almost 20 years and deeply admire the company 's phenomenal commitment to Formula One . I look forward to much success together in the years ahead . '' Lowe adds to a wealth of experience in the Mercedes hierarchy . Brawn oversaw all seven of Michael Schumacher 's world titles in addition to Jenson Button 's in 2009 . Mercedes sit fourth in the constructors ' championship ahead of Sunday 's Monaco Grand Prix , the sixth race of the 2013 season . `` I am delighted to welcome Paddy to the team and to begin working together , '' said Brawn . `` He has an excellent record of success in the sport and would be an asset to any of our rivals in the pit lane . `` Paddy 's arrival will further strengthen our organization and puts us in a strong position for the future . '' While Mercedes are able to invest in pursuit of race wins , other teams face more stark financial realities . This time last year Williams were celebrating Pastor Maldonado 's win at the Spanish Grand Prix . Twelve months on Maldonado and rookie teammate Valtteri Bottas both failed to make it out of the first round of qualifying last time out in Barcelona . While results on the track have been disappointing , deputy team principal Claire Williams insists financial solvency is of greater importance . `` The budget is always the most important thing -- securing more revenue than I did last year , '' Williams , whose father Frank Williams founded the team , told Formula One 's official website . `` That is really important to me -- getting as much money in for the team as I possibly can . The more money you have the better your race car can be , in effect . `` Secondly , making sure politically that the team is in the best position . And thirdly - and probably most importantly -- results . `` Being at the top of the grid and fighting for world championships . I 'm not going to give up until we 're back again . '' Bottas is yet to score a point in Formula One , with his best finish of 11th coming at the Malaysian Grand Prix . Williams praised the young Finn , suggesting he will be challenging at the front of the grid as his career progresses . `` I think we definitely have a future world champion at hand -- but of course we have to give him the car to allow him to prove his talent , '' declared Williams . `` He has done a good job so far . He has finished every race , made up positions with great overtaking manoeuvres , and is giving strong feedback to the engineers in order to improve the car . ''
Paddy Lowe cleared to join Mercedes from McLaren on June 3 . The British driver will be joined by his former team mate Lewis Hamilton at the German Grand Prix in July. ( technical ) Williams deputy team principal says finances more important than race result . Claire Williams also describes Valtteri Bottas as a future world champion .
