Labour's deputy leader struggled to give the figures on how much a bankers' tax would raise or how much a job creation plan would cost.
Speaking to Jo Coburn of the Daily Politics from a Labour meeting in Coventry, Harriet Harman said: "I will have to get back to you on that."
And when asked about the cost of the job creation guarantee plans, she said "there was no mystery about it" although she was unable to give any figures on the cost, but claimed Ed Balls and Ed Miliband knew.
Later in the interview, Ms Harman said the figures were "at hand, just out of reach here - and you know it is a carefully costed-programme".
