Authorities in Bahrain have ordered armoured vehicles onto the streets around the Grand Prix race track. Conservative MPs have criticised the Chancellor's decision to lend an extra £10bn to the IMF. And, can you really build a cathedral out of cardboard?
0709 Many people are still saying the Grand Prix in Bahrain should be cancelled, despite it being only 24 hours away. The BBC's correspondent in Bahrain, Dan Roan, gives us the latest.
0711 A passenger plane has crashed in Pakistan killing all 127 people on board. Aleem Maqbool, the BBC's correspondent in Islamabad, explains how this might have happened.
0714 The Chancellor George Osborne may have made many friends by agreeing to lend another £10bn of taxpayers' money to the IMF; but he has also made enemies on his own backbenches. The BBC's political correspondent Tim Reid explains.
0717 George Osborne is continuing to defend the controversial budget plan to cap tax relief on charitable giving. We have heard much recently about the political fallout of the measure, but what exactly might be its impact on the arts world? The BBC's arts editor Will Gompertz has been crunching some hypothetical numbers.
0720 Conlon Nancarrow was a musician, born a hundred years ago, who wrote music specifically for the player piano. The fast speeds and rhythms meant it could only be played mechanically, after the notes had been transferred to a roll fed into a specially adapted piano. So you might say the Southbank in London is taking a bit of a risk marking the centenary of his birth by staging a demonstration of it this weekend to mark Nancarrow's centenary. Today reporter Nicola Stanbridge went to listen.

0732 South Sudan's President Salva Kiir has ordered the withdrawal of his troops from the Heglig oil field across the border in Sudan. South Sudanese forces captured the oil field last week, accusing Khartoum of using it as a base to launch attacks. UN chief Ban Ki-moon has described the occupation as illegal and also called on Sudan to stop bombing the South. Will this be enough to dampen the tension between the north and the south and what is the long term solution to lasting peace? The BBC's correspondent James Copnall has the latest from Juba. Also on the programme, Wol Mayar Ariec, South Sudan's representative in Britain.
A paper in Nature this week
suggests that cosmic rays are not at all like what we thought they were like.
At the same time, another paper in the Journal of Astrophysics shows that dark matter is not where it should be - and so probably is not anything like we thought it was either. In the pioneering field of astrophysics, are there any certainties or will our theories constantly be challenged? Professor John Butterworth, professor of Physics at UCL and has worked on the Large Hadron Collider at Cern, explains.
0742 Christchurch in New Zealand is to get a replacement cathedral - made out of cardboard. It will be an interim replacement which will hopefully last 20 years, while something more permanent is sorted out. It is not the first cardboard building - a school was built in Westcliff-on-Sea ten years ago, and is half way through its life. Helen Gribbon, group leader at Buro Happold, an engineering firm that has worked with cardboard construction, explains how a cardboard building works.
0745 Review of the papers.

Richard O'Dwyer is a student in Sheffield in his twenties fighting extradition to the US. The American authorities say he made thousands of pounds through a website that enabled people to illegally download copyrighted films and TV programmes. He says he cannot be responsible, and his case is attracting some high profile supporters. Next week he has been invited to meet the chair of the Home Affairs Select committee at Westminster. Is he a victim of the arrangements between the US and the UK or not?
Mr O'Dwyer's mother, Julia O'Dwyer, explains why she thinks her son should not be extradited.
Armoured vehicles have been deployed around the capital of Bahrain, Manama, and on the road to the nearby motor racing circuit, amid continuing anti-government protests ahead of tomorrow's Formula One Grand Prix. Eyewitnesses say police, who had petrol bombs thrown at them during demonstrations yesterday, responded with tear gas. There are growing calls for the race to be cancelled.
Fahad al-Binali, Bahraini Information Authority Affairs spokesman, outlines the state's views.
It is Record Store Day today. An annual event where independent record stores team up with musicians and record labels to bring out exclusive, one day only releases in the hope of luring music fans away from the internet and into real life record shops. This year sees special CD and vinyl releases by the likes of Abba, Bruce Springsteen and The Sex Pistols. But
as Mark Coles reports the 78rpm record is making a surprise comeback too.
Sandra Newman claims to have done some of the work for people, she has written a new book which guides readers through everything from Greek Tragedy to Proust. Ross Leckie is the author of the Bluffer's Guide to Classics. They discuss Remembrance of Things Past, Don Quixote and Paradise Lost. But, whereas Sandra's read them all Ross has only read one. Can the presenters guess which one he has bothered to pick up?
0851 The trial of Anders Breivik for the murder of 77 people in Norway last year has given us further insight into not only Norway's judicial system but also its media and politics. How far is what we have seen over the course of the week different from how we treat criminals and those responsible for mass killings? Thomas Hylland Eriksen, professor of Social Anthropology at the University of Oslo, and John Cooper QC, Criminal and human rights barrister and visiting professor of law at Cardiff University discuss.
