Rio Olympics 2016: Chris Langridge and Marcus Ellis reach semi-finals
Chris Langridge and Marcus Ellis beat Japan's Hiroyuki Endo and Kenichi Hayakawa to become the first Britons to reach an Olympic badminton semi-final since Athens in 2004.
The British pair, 22nd in the world, won 21-19 21-17 and now face China's Fu Haifeng and Zhang Nan on Tuesday.
Meanwhile, GB's Rajiv Ouseph moved in to the men's singles quarter-finals.
He beat seventh seed Tommy Sugiarto 21-13 14-21 21-16 and will next play European champion Viktor Axelsen.
Ouseph, 29, faces the Danish fourth seed, who beat Ireland's Scott Evans 21-16 21-12, on Wednesday.
Langridge and Ellis have a chance to secure Britain's first Olympic badminton medal since Nathan Robertson and Gail Emms won mixed doubles silver in Athens 12 years ago.
"Our record against the Chinese pair is not as good as we would like but the thing is, this is the Olympics and anything can happen," said Langridge.
"If you had told me before the start that we would make the semi-finals I would have bitten your hand off.
"It is amazing - we are one of these pairs that are quite up and down - but this tournament we have shown our ability."
