Chris Adcock and Imogen Bankier suffered a setback in Shanghai today when they suffered a first-round defeat at the Li Ning China Open, the fifth Premier Superseries event of the year.

The Anglo-Scottish pair, the highest-ranked of the three GB pairs chasing Olympic qualification at No. 13, went down 21-17 21-16 against Malaysia's Chan Peng Soon and Goh Liu Ying.

Adcock and Bankier, the world silver medallists, were always behind from 2-2 in the first game. In the second game they recovered from 12-8 down to lead 13-12 but the Malaysians surged again to win on their first match point after just 36 minutes. Today's first-round exit followed their opening round defeat at last week's Yonex Sunrise Hong Kong Open.

Nathan Robertson and Jenny Wallwork, ranked No. 18, also fell at the first hurdle today.

The Commonwealth silver medallists, who are ranked No. 18 in the world, went down 22-20 21-13 against Thai pair Maneepong Jongjit and Savitree Amitapai.

Robertson and Wallwork came back from 19-16 down to draw level at 19-19 then saved a game point at 20-19 before the Thai pair took the opener on their second opportunity.

The Engish National champions, who will defend their title at the Bolton Arena in early February, moved into a 3-1 lead in the second game before Jongjit and Amitapai drew level at 3-3 before pulling away to take the second game and the contest 21-13.

The second Anglo-Scottish pair of Robert Blair and Gabby White, who ar e No. 20 in the world, were in action in the evening session on first-round day at the final event of the year at the OSIM BWF World Superseries 2011 circuit.

They faced seventh seeds Songphon Anugritayawon and Kunchala Voravichitchaikul and despite winning their two previous meetings with the Thai pair, Blair and White went down 21-19 21-18.

In the first game Blair and White were well placed at 15-15 before their opponents rattled off five unanswered points to reach game point.

In the second game Blair and White made a real fight of it, pulling back from 10-5 down to level at 13-13 then recovering from 17-14 to 17-17. But the Thai pair hit back with a final surge to clinch victory.

Adcock returned to the court with Andrew Ellis for men's doubles. But the England pair faced a tough test against Korea's second seed Jung Jae Sung and Lee Yong Dae and went down 21-11 21-17 despite a plucky effort in the secodn game when they pulled up to within a point at 18-17 before he Koreans took the next three points to move into the second round.

Wallwork and White were the last England hopes as they tackled their women's doubles late in the evening, barely an hour after White's mixed doubles match.

And the England pair went down 21-13 21-14 against Misaki Matsutomo and Ayaka Takahashi after the England pair had led 9-7 in the second game as they tried to turn things round.

Meanwhile, Rajiv Ouseph, who contested last week's Hong Kong event, has returned home to tackle the Scottish International Championships in Glasgow, where he was the 2008 men's singles champion and is this week's top seed.

Commonwealth bronze medallist Elizabeth Cann is bidding to recapture her women's singles crown in Glasgow while top GB women's doubkles pair Mariana Agathangelou and Heather Olver are women's doubles favourites at the Kelvin Hall, having been runners-up last year.
