In my view the timing of the oil price is because of a recent meeting of OPEC (of which UK has strong links with Saudi Arabia and Iraq). The oil market has seen increased supply from the USA and Canada with increased "unconventional" fossil fuels: tar sands (oil sands) and fracking (shale gas). As we know, these are very damaging to the climate and the North American water table. If Osborne wants to take credit for the cut in fuel prices in the UK, he can take the blame for his long term economic plan which threatens future generations. As for infrastructure need i mention the "road to recovery". I think we all see the reality of serious pot holes thanks to Osborne's austerity and neoliberalism.
