Shi, beaten by Malaysia's Lee Chong Wei in the 2017 final, has had a superb run at the All England, beating top-ten seeds Chen Long, Son Wan Ho and Lin on the way to the title.

In the mixed doubles final, history was made as Yuta Watanabe and Arisa Higashino became the first ever Japanese mixed doubles partnership to win the title.

The young pairing defeated fifth seeds Zheng Siwei and Huang Yaqiong of China 15-21, 22-20, 21-16.

"I'm happy that we are the first winners of the mixed doubles here for Japan, but we are not going to be satisfied by this result," said Higashino, 21.

The young pairing are still only 48th in the world rankings.

Tai Tzu Ying from Chinese Taipei retained the women's singles title after beating Japan's Akane Yamaguchi 22-20, 21-13, the first player to defend the champion since Lin Dan's wife Xie Xingfang completed a hat trick of titles in 2007.

Top seed Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo of Indonesia also defended their men's doubles title with a 21-18, 21-17 victory over Denmark's Mathias Boe and Carsten Mogensen.

The women's doubles title went to Denmark's Kamilla Rytter Juhl and Cristinna Pedersen, who defeated Japanese duo Yuki Fukushima and Sayaka Hirota 21-19, 21-18.
