SIR – Now that the Lib Dems have become an irrelevance, which they always were in spite of their many seats in the House in the last Parliament, it is high time to revive discussion of the introduction of identity cards, which mainly the Lib Dems and Liberals before them always opposed.

The citizens in the many civilised countries that rightly have IDs do not appear to suffer from loss of civil liberties.

Proper IDs are an essential part of life, as they prove you are who you say you are.
