Conservative leader Dave Cameron thinks there are two likely scenarios for the outcome of the next general election - a small overall majority for his party or a large one. He is planning for government based on both scenarios. Talks with permament secretaries will start next January, although how much they are told about Conservative plans will depend on how receptive they are.
Dave Cameron thinks that Tony Blair ran a brilliant campaign, but was insufficiently prepared for government. Possibly Blair's mistake was to follow Conservative spending plans for his first term (which they would have topped up anyway) and then to over react in his second term by increasing spending rapidly, leading to the current problems with the public finances.
