World and Olympic badminton champion Lin Dan of China clinched his fourth All England title with a 21-19 21-12 victory over world number one Lee Chong Wei of Malaysia in the final in Birmingham.
The match was a re-run of last year's Olympic final in Beijing where Lin swept to a 21-12 21-8 success.
It was a ninth triumph over his big rival in their last 10 meetings and a boost for the Chinese as he seeks to regain his place at the top of the world rankings.
Lin, making his sixth appearance in a row in the final, had won the title previously in 2004, 2006 and 2007.
In the women's final the unseeded Chinese Wang Yihan beat world number one Tine Rasmussen of Denmark.
China won both doubles and the mixed doubles.
