England's Rajiv Ouseph caused a first-round shock at the All England Championships by beating third seed Son Wan-Ho in the men's singles.
Ouseph, 28, who won silver at the 2010 Commonwealth Games in Delhi, beat the South Korean 21-16, 18-21, 21-19.
"It's probably the biggest win I've had so it's a dream, really," he said.
English married couple Chris and Gabby Adcock beat unseeded Indonesians Markis Kido and Pia Zebadiah Bernadeth 21-15, 21-8 in the mixed doubles.
Ouseph and the Adcocks are aiming to be the first British winners of the All England event - badminton's answer to Wimbledon - since Nathan Robertson and Gail Emms took the mixed doubles title in 2005.
"All the British players wants to do well here in front of this incredible crowd," Ouseph told BBC Sport.
Chris Adcock added: "It's the biggest event on the calendar apart from the World championships.
"There's no pressure on us because we're sixth in the world, but if we continue to play well we're in with a shout."
Men's doubles pair Andrew Ellis and Peter Mills lost 21-9, 21-17 to fourth seeds Mohammad Ahsan and Hendra Setiawan of Indonesia.
Fellow English players Matthew Nottingham and Harley Towler lost 21-11, 21-18 to China's Fu Haifeng and Zhang Nan.
There were also defeats for Fontaine Chapman, Chris Cloes and Sophie Brown.
The event runs until 8 March, with all finals talking place on Sunday.
