England's Marcus Ellis and Lauren Smith reached the semi-finals of the All England Open with a brilliant comeback victory over Hong Kong duo Tang Chun Man and Tse Ying Suet.
The English pair lost the opening game 26-24 before facing match point in the second, but fought back to take it 22-20 and then won the decider 21-11.
"It's incredible and something you dream of," Smith told BBC Sport.
The result should effectively secure them a place at Tokyo 2020.
