When the hon. Gentleman replied to a question from my hon. Friend the Member for Pontefract and Castleford (Mr. Lofthouse) about the interaction between benefits and tax reductions, the Under-Secretary of State for Social Security, the hon. Member for Maidstone (Miss Widdecombe), shook her head vigorously. Perhaps the hon. Gentleman can persuade the Minister to explain why she shook her head.
