Again - the UKBA's own guidance speaks to intent:

Yes, the reason for wanting to become a resident is not dispositive.
But there must still be an intention to become a resident - the relevant treaty rights are for residents; and not merely an intention to be a visitor.

Firm plans to move on after a short period is evidence that points away from intent to reside.

Hi Holly, I'd be really interested to understand why you so firmly believe this to be the case. Is it based on personal or professional experience or a document or law I've missed? I'm just an interested amateur with a particular liking for the EU's freedom of movement and a dislike of the UKBA's ever more authoritarian stance. I've read through the EC Directive 2004/38/EC; the judgements for Singh, McCarthy and Eind; the UKBA's Eurpoean Caseworker instructions and the UKBA's published internal guidance as well as any forum posts I've seen over the past year. I can't find anything which talks about the concept of residence in the style you are refering to (.i.e differentiating rights based on temporary vs permanent residence) or a requirement to intend to reside for any length of time, in fact the whole concept of residence seems to be pretty much based around allowing maximum transcience.
