|Mutumwa Mawere discusses|
Zimbabwe's political future
Zimbabwe's recent troubles have been well documented in the media.
The country's economy is in tatters with inflation said to be running at 150,000 per cent and unemployment rife.
Exacerbating this, dissent is rarely tolerated by President Robert Mugabe's Zanu-PF government.
Simba Makoni, the former finance minister, this month said he would stand as an independent candidate in the upcoming elections.
Makoni becomes the first high-profile Zanu-PF member to publicly challenge Mugabe, raising hopes for more competitively fought elections.
Mutumwa Mawere, the chairman of the Africa Heritage Society, joins Sir David to discuss the new candidate and the prospects for political change in Zimbabwe.
Radwan Siddiq, Sheikh Hasina's nephew, talks
about his aunt's role in Bangladeshi politics
Last July, Sheikh Hasina, the former prime minister of Bangladesh, was arrested on charges of corruption.
This came as part of a clampdown by the interim government, which has pledged to clean up Bangladeshi politics before the elections at the end of 2008.
Supporters of Sheikh Hasina claim the charges are politically motivated and part of a campaign to rid the country of its most popular leaders.
However, this week a Bangladesh high court declared the corruption trial of Sheikh Hasina unlawful.
If the supreme court upholds the decision it could jeopardise the government's efforts to tackle high-level corruption.

awarded honorary Palestinian citizenship
Daniel Barenboim is regarded as one of the world's finest classical musicians.
Through his music he has sought to transcend religious and political difference.
In 2001 Barenboim broke a long-running taboo by conducting a piece by Wagner in Israel.
He also assembled an orchestra consisting of young Arabs and Israelis.
Recently, Barenboim was awarded honorary Palestinian citizenship after holding a concert in Ramallah.
Barenboim joins Sir David to discuss his hopes for a lasting peace settlement between the Israelis and Palestinians. He also talks about the role music can play in bringing people together.

The current presidential race is one of the most exciting for years. With a strong crop of candidates and an electorate hungry for change, the US is already gripped with election fever.
After all the expectation and excitement of "Super Tuesday" both parties' nominations are still up for grabs.

They discuss the implications of Tuesday's results and examine the relative strength of each of the political parties.
