Rejected second-level domains
.soc.uk - proposed for Social and Society use.
.me.uk - proposed by Personal Domain Names Ltd.[1] - similar to the one that was chosen but outsourced to the proposer.
.scot.uk - A domain for Scotland; it did not have the support of the Scottish internet community, many of whom favour a wholly separate Scottish ccTLD (see .sco). It was another attempt to outsource an SLD to the proposer.

[edit]
Individual institutions
.bl.uk and .british-library.uk - British Library
.icnet.uk - Cancer Research UK
.jet.uk - Joint European Torus
.nls.uk - National Library of Scotland it also held another domain .national-library-scotland.uk which has now been deleted.
.parliament.uk - Parliament of the United Kingdom (the placement of parliament.uk outside of .gov.uk reflects the British constitutional convention of the importance of parliamentary sovereignty over, and independence from, the executive government. Note that .scottish.parliament.uk relates to the devolved Scottish Parliament, not to part of the UK Parliament.)
