A prominent Iranian resistance leader is on Monday expected to meet German members of parliament in Berlin, threatening to strain ties with Tehran at a crucial juncture in efforts to curb its nuclear ambitions.

On her first visit to Germany from her base in Paris Mrs Maryam Rajavi, president-elect of the National Council of Resistance of Iran, an umbrella organisation of the People’s Mojahedin Organisation of Iran, will urge Germany to reject the rule of the mullahs and support democratic change.
