<P> Karen Clark (Mimi Kennedy), the US Assistant Secretary of State for Diplomacy, who is against military intervention, is leading the meeting and flags a report by her assistant Liza Weld (Anna Chlumsky) titled "Post-War Planning, Parameters, Implications and Possibilities" (PWPPIP). The report heavily opposes intervention, noting the lack of intelligence except that which is coming from an unsubstantiated source known as "Iceman". Also during the committee it is hinted at that the US Assistant Secretary of State for Policy, Linton Barwick (David Rasche), may have set up a secret war committee . After being ambushed by reporters, Simon contradicts his previous statement by saying the government has to be prepared to "climb the mountain of conflict" and is again subjected to chastisement from Tucker . </P> <P> Returning to the US, Karen and Liza conclude that Linton has created a war committee under the guise of Future Planning . At a party Karen teams up with General George Miller (James Gandolfini) who opposes the war believing that the US does not have enough troops to succeed . She tells him that they could use Simon on the committee as he would "internationalise the dissent". While on a fact - finding mission in Washington, Simon and Toby are invited by Karen to the Future Planning committee . Toby accidentally leaks the details of the meeting to a friend at CNN before meeting up with Liza at a bar; they end up sleeping together . Due to Toby's leak the Future Planning committee is swamped, but Karen and George fail to find out anything about the war . Both Karen and Linton turn to Simon to back their respective causes, but he struggles to say anything meaningful and ultimately does not take a side . Tucker, also in the US, is diverted by Linton to the White House for a fake briefing . He confronts Linton, who tells him that he must supply the US with the British intelligence on the situation in the Middle East, with which Linton will influence the vote on intervention . </P> <P> Simon, back in his constituency of Northampton, is harassed by a constituent, Paul Michaelson (Steve Coogan), about the state of one of Simon's constituency office walls which he claims is on the verge of collapsing into his mother's garden . News of this reaches the papers, who criticise Simon for not acting on the issue . Suzy finds out about Toby's one - night - stand with Liza and they break up . When leaving their apartment he gives her a copy of PWPPIP to leak if she chooses, but she calls him a coward for not doing it himself . </P> <P> The President rushes forward the security council vote on military intervention by vetoing tariffs on Chinese imports . Simon tells his Director of Communications Judy Molloy (Gina McKee), to leak to the press that he would resign if the committee votes in favour . Once at the UN Headquarters Tucker gets word that PWPPIP has been leaked, making a yes vote unlikely . It is later revealed that Michael Rodgers (James Smith) of the Foreign Office accidentally leaked it, not realising its importance . Miller and Tucker convince Jonathan Tutt (Alex Macqueen), the UK Ambassador, to push the meeting forward so that the leak will not have time to spread in the US . However, Linton asserts his dominance over Tucker by telling him that the British intelligence has to be handed over before a vote can be taken . Able to make Jonathan reverse his changes and delay the meeting, Tucker, with the help of Senior Press Officer Jamie McDonald (Paul Higgins), fabricates the details of PWPPIP by forcing Michael to remove all the arguments against intervention and presenting it as the intelligence . Subsequently, the committee votes in favour of intervention . </P>
