[1][3] Nasha worked as a journalist and civil servant before entering politics, and also served a term as Botswana's High Commissioner to the United Kingdom.
[4] After a falling out with President Ian Khama, she lost the BDP speakership nomination to Gladys Kokorwe in 2014, and in 2016 defected to the opposition Botswana Movement for Democracy.
[7] In her autobiography, Nasha recalled that girls at the time were only taught to read and write in order to be able to correspond with their future husbands, who it was presumed would have to migrate to South Africa to earn a living.
[8] At the 1999 general election, Nasha won the seat of Gaborone Central, defeating Michael Dingake of the Botswana Congress Party (BCP).
[15] In November 2014, following the 2014 general election, the BDP refused to re-nominate Nasha as speaker and instead nominated Gladys Kokorwe (President Khama's preferred candidate).
The attorney-general, representing the government, argued that Nasha had ceased to become speaker on the day of the election and thus no longer had a say over parliamentary procedure, but a court ruling rejected this argument.
[17] In January 2016, Nasha resigned from the BDP to join the opposition Botswana Movement for Democracy (BMD), which forms part of a broader alliance, the Umbrella for Democratic Change (UDC).
