<p>This paper explores the extent of current UK government spending on science and technology placed in its recent historical context. The allocation of this spending across the different arms of government, the primary purposes of the expenditures undertaken and the extent to which the government performs as well as funds R&D are also explored, with some international comparisons analysed. The political and institutional processes that determine the revealed patterns of expenditure in the UK, the rationales behind such spending and the aims and objectives of the main spending departments are discussed, as is the interaction with EU expenditures on science and technology. The effectiveness of or pay-off to government support of this kind is also considered before future spending plans are addressed.</p>
