I wish I could say that Mr Brown and Mr Cameron were likely to be equally embarrassed by this report in The Times:

Lord Tebbit declared that Mr Cameron was regarded as out of touch by ordinary people and that it was only natural that Mr Brown should make himself the “heir to Thatcher”.
Many people believed that the Conservative leader and his colleagues did not know how the other half lived, Lord Tebbit said.

He drew a wounding comparison between Mr Brown, on whom he lavished praise, and Mr Cameron, whom he criticised for his lack of experience and his stand on grammar schools. “I think we lack somebody of the standing of Margaret,” he said when asked to name the Conservatives’ biggest asset.

But I fear that Mr Brown is unembarrassable, even at the shameful prospect of being praised by Lord Tebbit.
