But they could not maintain a promising start against Doris and Stefanie Schwaiger losing 21-15 21-12.

"It's been an incredible week for us. We brought our game home to Britain and it's been just amazing for us, thanks to everyone."
Dampney added: "Every time we stepped on court it's given me goose pimples.
"We've loved every second and that's down to you guys and our family and friends. It's been amazing."
