The Co-operative Party has maintained its representation in Parliament at about the same level as before the election. Out of the forty-three candidates selected to fight seats at the election, twenty-eight were successful. Six sitting MPs lost their seats on the night and eight candidates drawn from the Parliamentary Panel were unsuccessful. The twenty-eight MPs now represent a greater proportion of the Parliamentary Labour Party as a whole. The number of female Labour and Co-operative MPs increased to eight.
Of the five Labour leadership contenders, only Ed Balls is a member of the Co-operative Party.
