IRNA � Iran's newly-appointed ambassador to London Hamid Baeedinejad on Thursday presented his credentials to Britain's Queen Elizabeth II.

Baeedinejad had earlier presented a copy of his credentials to British Foreign Secretary Boris Johnson to officially begin his mission in the country.

Iran and Britain reopened embassies last summer after four years of icy relations and a year later upgraded diplomatic ties from charge d'affaires to ambassadorial level.
