World in motion
The world is on the move as never before, and tonight Newsnight devotes much of the programme to finding out what it means for both the developed and the developing world.
Where are we going?
Almost 200 million people migrated in 2005 - double the amount that moved in 1980, but is this a good or a bad thing? Does it alter the character and identity of countries? Can or should we stop it?
Several things conspire to make this a good night to explore mass migration. Spain has asked for help from the EU to stem the flow of immigrants from Africa. George Bush is at the Mexican border today as part of his crackdown on illegal immigrants. France's lower house has voted in a law to attract skilled immigrant workers and keep less skilled ones out. And South Africa is struggling to deal with the Zimbabweans fleeing Mugabe's regime.
We'll be speaking to correspondents and politicians on different continents.
Also today some of the worst violence since the fall of the Taliban in 2001 has erupted in Afghanistan with at least 104 dead. David Loyn reports from the country on the alarming levels of corruption and the concerns over the way reconstruction money is being spent.
A great parliamentarian
The Conservative MP Eric Forth has died. In an age where backbenchers are more renowned for their slavish loyalty to their parties rather than independence of mind, Mr Forth stood out. David Grossman will pay tribute to a great parliamentarian.
And from the most memorable front page shortlist - Gurindar Chadha - star of Bend it like Beckham - selects the Daily Mail's extraordinary front page on the Stephen Lawrence suspects.
