China's defending champion Chen Yufei failed to retain the title at the All England badminton championship after losing to Chinese Taipei's Tai Tzu-ying 21-19, 21-15 in the women's singles final in Birmingham on Sunday 

The 25-year-old Tai has replaced Chen as new world number one following the victory. 

With previous two All England titles in 2017 and 2018, second-seeded Tai was on a revenge mission in Birmingham after losing last year's final against Chen.  

Meanwhile, Denmark's Viktor Axelsen wins his first All England title following a straight-set 21-13, 21-14 victory over top seed Chinese Taipei's Chou Tien-chen in the men's singles final. 

Twenty-six-year-old Axelsen won the first set by controlling play with very few unforced errors and tsunami of smashes that wrong-footed his hapless opponent. 

In the second, Chou desperately needed to get back in the game but the Dane's continued control was not eased. 

It was the second year in a row that the Dane appeared in the All England final, who lost to Japanese Kento Momota last year. 

The world number seven said this was a day he would never forget. 

"This means a lot to me. It is a big dream come true and it's up there with all my biggest achievements in my career so far," he said after his maiden tournament win in a Super 1000 event. 

Meanwhile, Chinese duo Du Yue and Li Yinhui lost to Japanese Yuki Fukushima and Sayaka Hirota 13-21, 15-21 at women's doubles final. 

Indonesia's Praveen Jordan and Melati Daeva Oktavianti defeated Thai third seeds Dechapol Puavaranukroh and Sapsiree Taerattanachai 21-15, 17-21, 21-8 in the mixed doubles final. 

This is the first time that Chinese shuttlers fail to gain any gold medals at All England since 1995, the worst performance in 25 years.
