ISLAMABAD: A spokesman for President Asif Ali Zardari said the leader has returned from Dubai and is not worried about a political crisis gripping the country.

Farhatullah Babar said the president, who spent more than a week in a Dubai hospital for treatment last month, returned in the early hours of Friday after a brief visit to attend a wedding.

Asked whether Zardari was concerned, Babar said, ''Absolutely not. Why should he be?''
