STC Plc did little at its results meeting to discourage speculation that its analysis of Plessey as a takeover candidate had come out positively, but Plessey isn’t the only company on the STC horizon: it is possible to make an equally good case for STC to make a move for the combined Ferranti International Signal Plc, which has similarly attractive defence interests, a stronger presence in the US, and might be more attractive to STC on the grounds that it isn’t in the semiconductor business any more.
