A political row is brewing over an Algerian man jailed yesterday for stabbing a policeman to death and planning poison attacks in Britain. Home affairs editor Alan Travis will be analysing on Electionblog Michael Howard's claim that failures in government immigration policy are to blame for the fact that the Algerian Kamel Bourgass was allowed into Britain.
Elsewhere on the campaign trail, the Lib Dems launched their manifesto, promising tax cuts and the withdrawal of troops from Iraq. And later on, we'll have an audio dispatch from the Guardian's sketch writer Simon Hoggart, who's landed the plum task of attending Robert Kilroy Silk's launch of the Veritas manifesto, in which immigration also plays a big part.
We've two world dispatches today: Jonathan Watts in Beijing looking at the background to current Sino-Japanese tensions and, shortly, Jon Henley in Paris on the enduring inclination of British and French people to travel to each other's countries and write books about their experiences.
We'll also be testing your ornithological expertise in our "do you know your bird breeds?" quiz, a propos of this story.
