Ken Clarke indicated that married tax allowances may be a casualty of the tight economic conditions   Cabinet minister Kenneth Clarke has backed away from comments suggesting that the Conservatives may not make good on a promise to give tax breaks to married couples during the course of this Parliament.

In an interview with the Daily Telegraph, Mr Clarke suggested that married couples should not "count on" receiving the break before the 2015 poll, claiming that he did not remember anyone in the Government promising it.

His comments seemed to be at odds with the Tory manifesto promise in the 2010 election of a transferable tax allowance that could be worth £150 a year to married couples where one spouse stays at home.  But a spokeswoman today said Mr Clarke accepted that the change will happen, and was not intending to make a statement of policy in his comments.

The measure was opposed by Liberal Democrats, but was not ruled out in the Coalition Agreement, which stated merely that MPs from Nick Clegg's party would be free to abstain when measures were brought forward in Parliament.

In his interview, Mr Clarke appeared to indicate that married tax allowances were likely to be a casualty of the tough economic conditions.

Despite the better-than-expected growth of 1% in the third quarter of 2012 announced earlier this week, he said it was too early to be certain the economy is bouncing back and predicted "a long hard road" ahead.

"We never committed ourselves to married couples' tax by the end of the Parliament," the minister without portfolio told the Telegraph.

"I'm married, I'm not counting on it. I don't remember anyone promising that kind of thing."

However, a spokeswoman for Mr Clarke said today: "It was a comment, not a statement of policy. Any tax changes are a matter for the Chancellor. He accepts the changes will happen."

On the economy, Mr Clarke - a former chancellor - said: "It would be absolute folly to turn around and say it will all be fine by Christmas. Anybody who says we are absolutely certain we are bouncing back to strong growth is being very optimistic."
