News in Picture

Gordon Brown has delivered what had been billed as his first big speech on immigration, in which he acknowledged concerns about immigration and promised to beef up the UK's rules.

He specifically pledged to tighten up the points-based system for determining which migrants can work in Britain, offering work visas to people in occupations where there are shortages, but not to others.

But does the points-based system work in practice? Tonight, Richard Watson reveals new evidence of failures in the student work visa system, which leave it open to widespread fraud.

Also, the US ambassador in Kabul has thrown a hand-grenade into the White House's deliberations over the proposed troop surge for Afghanistan.

In a leaked cable, Karl Eikenberry said President Hamid Karzai's government should first prove it would tackle corruption.

Mark Urban reports tonight on how President Barack Obama will navigate his way through all this conflicting advice, and where this leaves the US and UK military strategies.

Plus, in times gone past the kings of Kabul would send their envoys to the city's only roundabout to find out what the ordinary people thought.

Lyse Doucet has been to the Sar-e Chowk roundabout to test the temperature as they did.

And we've sent our own envoy, Michael Crick, to take the temperature in Glasgow North East where voters are going to the polls to elect a new MP for the seat vacated by Speaker Michael Martin.
