Harriet Harman MP, Labour's Deputy Leader and Shadow Culture Secretary, said:
"Jeremy Hunt has broken the Ministerial Code and misled Parliament.
"It is not acceptable that these rules have been broken and we will call a vote insisting that Jeremy Hunt's breaches of the Code are referred to the Independent Adviser on Ministerial Interests
"The Ministerial Code sets the standards which Secretaries of State must live up to. When David Cameron came into power, he upgraded the Code and he said he was going to have higher standards in public office. Today those words ring hollow - he has just torn up the Code.
"Even if the David Cameron thinks it is acceptable for a Minister to break the Code he drew up, we do not and will call a vote."
