During the by-election, Lamont gave the response "Je ne regrette rien" to a question about whether he most regretted claiming to see "the green shoots of recovery" or admitting to "singing in his bath" with happiness at leaving the European Exchange Rate Mechanism. Cameron was identified by one journalist as having inspired this gaffe; it was speculated that the heavy Conservative defeat in Newbury may have cost Cameron his chance of becoming Chancellor himself, even though as he was not a Member of Parliament he could not have been.[8] Lamont was sacked at the end of May 1993, and decided not to write the usual letter of resignation; Cameron was given the responsibility to issue to the press a statement of self-justification.[9]
