LONDON: London fans had better watch out: Sacha Baron Cohen is unleashing his latest satirical incarnation on Leicester Square for the world premiere of ''The Dictator.''    

Cohen, who is known to court controversy, is expected to attend the red carpet event in character, but it's not yet known what his latest publicity stunt will be.

His new character follows in the footsteps of his other outrageous creations, Ali G, Borat and Bruno, and sees the comedian play Admiral General Aladeen, the freedom-hating military dictator of the fictitious North African Republic of Wadia.

Directed by Larry Charles, the film also stars Megan Fox, Anna Faris, Ben Kingsley and John C. Reilly.

Cohen hit the headlines earlier this year when he brought Aladeen to the Academy Awards red carpet holding, what he said were the ashes of North Korean leader Kim Jong-Il.

''The Dictator'' is being released in the UK and the US on May 16.
