Andy Sawford, Labour's Prospective ParliamentaryCandidate for Corby and East Northamptonshire has said that Louise Mensch was "obviously struggling to balance being MP with her family and business commitments."
Labour is now looking forward to the campaign ahead, fighting for action on jobs and the economy, supporting our local services which are facing massive cuts and working with local community organisations.
During the by-election we will focus on the two wasted years of Tory policies that have taken the country back into recession and left Corby suffering job losses in both the public and private sector.
This will be a tough election for Labour but we are determined to hold this Tory-led Government to account by showing the disastrous impact of their polices on the people of Corby.
