Prime Minister Datuk Seri Najib Razak is proud that the national badminton squad succeeded in uniting Malaysians despite failing to end the country's 22-year wait to lift the Thomas Cup.

"We are together in victory or defeat. I am proud of our Thomas Cup team. We will try again and congratulations to Japan," he said in a Twitter message after the Thomas Cup final.

Malaysia lost 2-3 to Japan in the 2014 Thomas Cup final at Siri Fort Indoor Stadium in New Delhi, India.

Meanwhile, the Prime Minister's wife, Datin Seri Rosmah Mansor when contacted by TV1 sports compere, Jasni Shafie, said luck was not with the Malaysian badminton team despite playing hard to win the cup.

Rosmah, who is Badminton Association of Malaysia (BAM) patron, said she was proud that the Malaysian players went all out especially the last singles player, Liew Daren.
