Question: The leader of India's main opposition Congress party   Sonia Gandhi   has retired from  her  post  the party confirmed on Thursday.
 Her  son   Rahul Gandhi   has been elected unopposed as the new president and will officially take charge on Saturday.
 Mrs Gandhi   71  has been the party president since 1998.  She  was elected to parliament in 1999.
 She  is  however  not retiring from politics and will continue as a member of parliament  the party said.
 Mrs Gandhi  entered politics in 1994   three years after after  her  husband  former Prime Minister Rajiv Gandhi  was assassinated.
 Her  power derived from being the head of the Nehru-Gandhi dynasty  which has led the Congress party and has ruled India for most of the years since it became an independent nation in 1947.
After distancing  herself  from politics following  her  husband's death   Mrs Gandhi  was initially seen as a reluctant and almost reclusive politician.
Under  her  leadership  the party turned in its second-worst performance since independence in the 1999 elections  but won the general elections in 2004 and 2009.

Mrs Gandhi  an Italian-born Catholic  would have been the first foreigner to become Indian prime minister had  she  not surprised everyone by turning down the post after  her  general election success in 2004. Yet  many considered  her  the de facto head of the Congress government.
In recent years  Mrs Gandhi  has faced health issues. In 2011   she  had surgery in the US for an undisclosed medical condition and in 2013  she  was taken to hospital from parliament after falling ill.

Answer: Sonia Gandhi


Question: (CNN) Germany's president Frank-Walter Steinmeier has warned of the fractures in its society -- highlighted by the electoral success of the far-right party Alternative for Germany (AfD) -- on the nation's Day of German Unity.
 Steinmeier  spoke of walls between cities and rural areas  between rich and poor  old and young  and online and offline communities.
They are "walls of alienation  frustration or anger" and behind those walls there is "deep mistrust of democracy and its representatives "  Steinmeier  said.
Without mentioning the AfD by  name  Steinmeier  warned that Germany's progress since 1990  becoming a democratic  peaceful and strong country at the heart of Europe  could be lost if politicians and ordinary Germans do not work together to fight the party's far-right ideology and to respond to the concerns of its supporters.
 Steinmeier  addressed this issue in  his  speech Tuesday  saying many Germans from the former East no longer feel at home in their own country  and question if anyone is looking out for them.
"This desire for a home  a homeland -- we mustn't leave that to the nationalists " said  Steinmeier .
"There must never be a route back to nationalism "  he  insisted  a statement that was met with a sustained ovation.
 Steinmeier  did  however  suggest Germany should consider stricter immigration controls in what can be seen as a bid to draw AfD voters back to the mainstream parties.
Germany should give asylum to those who are eligible   he  said  but must also consider "which forms of and how much immigration we want ... and need."
"Migration should be controlled according to our requirements "  he  continued  insisting that people who come to Germany must learn the language and abide by the country's laws and values. "That cannot be up for discussion."

Answer: Frank-Walter Steinmeier
