LONDON, May 29 (Reuters) - Anglo American on Wednesday rejected BHP Group's last-ditch request for more time to discuss a $49 billion takeover offer, dismissing it as highly complex and ending a five-week pursuit by the bigger rival.

Anglo had granted BHP a one week extension until 1600 GMT on Wednesday to its original May 22 deadline to submit a binding offer, after rejecting a third takeover proposal that had been dismissed as difficult to execute. (Reporting by Clara Denina and Felix Njini; Editing by Mark Potter)
