The three, who are incidentally the top three seeds in the German Championships, won their matches after some struggle against much lower-ranked opponents.

World No 2 Aaron Chia-Soh Wooi Yik battled past England’s Alex Green-Zach Russ 25-23, 21-14 in the opener.

They are expected to make it to the quarter-finals where they will meet unheralded Czech Republic pair Jiri Kral-Ondrej Kral in the next round.

World No 4 Goh Sze Fei-Nur Izzuddin Rumsani also had to stave off a great comeback by Scotland’s world No 63 duo Alexander Dunn-Adam Pringle.

They won 21-17, 22-20 in a match that lasted 40 minutes.

They can expect a tough ride in the next round as they face Denmark’s Daniel Lundgaard-Mads Vestergaard.

Earlier, Man Wei Chong-Tee Kai Wun beat their compatriots Wan Arif Wan Junaidi-Yap Roy King 21-16, 19-21, 21-16 to move into the second round.

However, another Malaysian pair, Ong Yew Sin-Teo Ee Yi, lost to Indonesia’s Bagas Maulana-Leo Rolly Carnando 16-21, 17-21.
