Brechfa, Trawscoed shake the order.

As expected, the morning run through the challenging Brechfa and Trawscoed stages led to changes on the final leg of Wales Rally GB - most notably in the JWRC where the title chase has once again been turned on its head.

Out front, BP Ford number one Marcus Gronholm continues to lead the way, although the Finn was given a brief scare on the first run through Trawscoed when he overshot a junction. Although the time loss was only 20 seconds, a minimal amount given his overnight lead, the incident is an indication that Gronholm can't afford to be complacent as he looks to wrap up the rally victory.

Behind Gronholm, one of the anticipated battles on the final leg was for second between Manfred Stohl and Petter Solberg, who lost the position on Saturday when he hit a gatepost in SS11 and damaged the steering on his Impreza.

Solberg was quicker than the OMV Peugeot on the run through Brechfa to bring the gap to Stohl down by over 16 seconds - pace which would put him ahead of the Austrian if he could maintain it through the following stages. However a spin on Trawscoed handed the initiative back to Stohl, who heads back to service with an advantage of over 50 seconds before the repeat run through the stages this afternoon.

A similar fight was expected for fourth place between Xavier Pons, who had been on the pace throughout leg two in the Kronos Citroen and Jari-Matti Latvala - the star of leg one in the Stobart VK Focus.

The 21-year-old Finn closed the gap to the Spaniard by one and a half seconds through Brechfa but then was given a helping hand in Trawscoed when Pons, like Solberg, suffered a spin that cost him valuable time.

As a result, Latvala is now back in fourth with an advantage of half a minute over the Citroen driver, although with two of the longest stages being re-run and conditions far from easy, the Spaniard could yet reclaim the place if he can rediscover his Saturday form.

Chris Atkinson made it through the morning stages unscathed to retain his sixth place, half a minute behind Pons and an equal distance ahead of seventh placed Francois Duval. The First Motorsport Skoda man is less secure in his positions however, with Dani Sordo having gone quickest through Trawscoed to close to within six and a half seconds of the Belgium. Amongst the WRC brigade, the only other change for position came on SS15, as Henning Solberg moved ahead of Matthew Wilson into eleventh - the young Briton admitting he was finding the conditions difficult on the final morning of the season.

The JWRC however was totally turned on its head once again after two more action packed stages for the S16000 brigade. On the opening stage of the day, a puncture slowed leader Jaan Molder who was then caught by champion elect Patrick Sandell, the Renault man ending the stage angry at being held up by the Estonian.

Molder's problem still promoted Sandell into the JWRC lead going into Trawscoed, with P-G Andersson having climbed into third past Luca Betti on the opening stage as he attempted to climb as far as possible back up the order after his leg one retirement.

As things stood, Sandell would still have lifted the crown but, possibly still feeling the effects of the incident on the previous stage, he rolled the Renault off the road and was unable to recover from a trip down a bank. However, before Andersson could take advantage, he too went off the road - with both drivers left stranded in the stage.

It means Molder now leads the JWRC with a comfortable lead over Betti and Briton James Wozencroft - although the implications for the championship are unclear due to the Superally regulations and the effect that that may have on Sandell's and Anderssons' stage times.

Should the pair be given 15 minute penalties for missing the final three stages, it would appear to leave Sandell with the advantage, although that is dependant on the Renault and the Suzuki being recovered from the stage and returned to Parc Ferme in Cardiff.

Sandell would be crowned champion as he would still pick up some points, leaving him level with Urmo Aava but with a superior head-to-head record when victories and second place finishes are taken into account.

Should Sandell not make it back to Parc Ferme but Andersson return to Cardiff, then the Swede could still be crowned champion while the failure of both to make it back would likely see Aava lift the title.

However, with two long and challenging stages still to run this afternoon, the situation could change at any time, with the destiny of the title only becoming clear once the teams return to Cardiff and the situation surrounding the various title protagonists is fully resolved.
