Labour's deputy leader attacked the Liberal Democrat position on the so-called bedroom tax and the top rate of income tax.
Harriet Harman asked Nick Clegg to clarify whether his party was for, or against, the policy that the government has called the spare room subsidy.
The deputy prime minister said the top rate of tax was 45%, rather than the 40% under the previous Labour government.
