Presented by Jeremy Paxman
First a quick word about something happening tomorrow - Justin Rowlatt will be popping up in Livingston, West Lothian, on Tuesday for Newsnight's very first edition of Pop-up Politics.
He and the team will be at The Centre in Livingston from 1pm onwards and would love it if you could join them - full details on our website www.bbc.co.uk/newsnight
But before that there is the matter of tonight's programme - here's what is coming:
Hot on the heels of Transport Secretary Lord Adonis saying a planned strike by British Airways cabin staff would "threaten the very existence" of BA, Prime Minister Gordon Brown has entered the fray, calling the strike "deplorable" and "unjustified".
Shadow chancellor George Osborne says Mr Brown cannot have it both ways - condemning the strike while at the same time taking money from Unite.
Tonight, Michael Crick examines the relationship between the union and Labour, and how the strike will affect it.
Also, in an interview on Woman's Hour today, Mr Brown signalled that he intends to "keep going" as leader even if Labour fails to secure a majority at the general election.
We'll be joined by political insiders to look at whether this was simply an answer to a direct question, or a message to colleagues and others in the event of a hung parliament.
Also, do public libraries have a future? Should they be saved at all costs or in the digital age are they a luxury that hard pressed local authorities cannot afford? Ahead of Labour's review of libraries, which is due out in a few days, David Grossman has gone to Swindon where there has been a recent campaign to save local libraries.
And Peter Marshall has a film from Washington on the links between British parties and their US counterparts.
Join Jeremy tonight at 10.30 on BBC2
