THE ‘You live and learn’ response by Oliver Letwin in relation to the disclosure that he was instrumental in persuading Margaret Thatcher to test out the Poll Tax on the Scots seems somewhat inadequate.

Unfortunately, with several other major lapses since then, he does not seem to be learning very well.
