2. These surveys used the ComRes question asking whether the respondent agrees or disagrees that the candidate "has what it takes to be a good Prime Minister".
3. These surveys used the Ipsos question asking: "On balance, do you agree or disagree that ...has what it takes to be a good prime minister?"
4. These surveys used the Ipsos question asking if a particular individual would be satisfactory as Conservative leader and Prime Minister.
