Sinclair Research Ltd is a British consumer electronics company founded by Clive Sinclair in Cambridge. Originally incorporated in 1973 as Ablesdeal Ltd. and renamed to Westminster Mail Order Ltd and then Sinclair Instrument Ltd. in 1975, it remained dormant until 1976, when it was activated with the intention of continuing Sinclair's commercial work from his earlier company Sinclair Radionics; it adopted the name Sinclair Research in 1981.
