Power couples: Ten spouses followed their partners into politics

Rosario Murillo has long been seen as a powerful influence on her husband, President Daniel Ortega.

Nicaraguan President Daniel Ortega has named his wife as his running mate as he seeks re-election for a third term in November.

First Lady Rosario Murillo is already widely seen as sharing power with her husband.

She is one among a growing number of spouses in the region who have run for office after their other half held the top job.

Below we take a look at 10 power couples in world politics throughout the decades.

Democratic Party presidential candidate Hillary Clinton wants to follow in the footsteps of her husband Bill, who was US president from 1993 to 2001.

Cristina Fernandez de Kirchner succeeded her husband Nestor Kirchner as president of Argentina in 2007. Some analysts thought the two planned to take turns in the top office but Mr Kirchner died in 2010 before he could run again.

Ms Fernandez was not the first woman to succeed her husband as president. Thirty-three years previously, Isabel Martinez became Argentine president after the death of her husband, Juan Peron.

The Philippines' former First Lady Imelda Marcos, whose husband Ferdinand was overthrown in 1986 after 21 years of rule, ran for the presidency in 1992, but finished fifth.

In Honduras, Xiomara Castro ran for president in 2013 after the ousting of her husband Manuel Zelaya, whose love of cowboy hats she shares. She narrowly lost to conservative candidate Juan Orlando Hernandez.

Guatemala's Sandra Torres divorced ex-president Alvaro Colom in order to run for the top office herself. Its constitution bars close relatives of the president from succeeding them. However, she did not win.

Segolene Royal ran for president of France in 2007, but was defeated by Nicolas Sarkozy. In 2011, she ran in the Socialist Party presidential primary election, which was won by her former partner, Francois Hollande. Now president, Mr Hollande has made Ms Royal environment minister.

Janet Museveni has been the First Lady of Uganda since her husband Yoweri Museveni became president in 1986. She has been an MP since 2006 and was recently appointed sport and education minister.

In South Africa, Nelson Mandela's former wife Winnie never ran for the presidency, but has been a powerful figure in politics in the ruling African National Congress.
