Britain's leading mixed doubles pairs will meet at the Swiss Open on Thursday as the battle for the likely one Olympic spot intensifies.

Chris Adcock and Imogen Bankier beat France's Baptiste Careme and Audrey Fontaine 21-16 21-13 to reach the second round in Basle.

Nathan Robertson and Jenny Wallwork then knocked out Stilian Makarski and Diana Dimova of Bulgaria 21-15 21-18.

The British pairings will meet at 1555 GMT on Thursday.

Robertson and Wallwork won their only previous competitive meeting in Malaysia in January, but they trail the Anglo-Scottish world number 19 partnership of Adcock and Bankier by two places in the rankings.

The pair ranked highest in the world on 3 May are most likely to be selected for Great Britain at London 2012.
