Mr Byles, who won the North Warwickshire and Bedworth constituency by 54 votes at the last election for the Conservative Party, announced he would step down next by posting a statement on his personal website.
The full statement said, “For the last four years, it has been an honour and a privilege to represent the people of North Warwickshire & Bedworth as both a constituency MP and a national legislator.
“Before becoming an MP I served in the Army for nine years, deploying on operational tours in Bosnia and Kosovo. By the time of the 2015 General Election, serving my country will have been the primary focus of my professional life for some 14 years. For myself and for my family, whose support and understanding have been unerring throughout, I believe it is now time to move on to new challenges. I will therefore not be standing for re-election in 2015.
“As I hoped it would be, my time in Parliament has been hard work but uniquely rewarding. I am proud of what we have achieved as a Government – putting Britain back on the road to recovery following the worst economic collapse the country has ever faced. I am particularly grateful for the personal contribution I have had the opportunity to make, as a member of the Energy and Climate Change Select Committee; Chair of three active All Party Parliamentary Groups; on the Bill Committee of the Energy Act 2014; and as the sponsor of a historic Private Members Bill on House of Lords Reform.
“With almost a year still to go before the General Election, I remain absolutely committed to my constituents and to tackling the important issues that face us locally, such as HS2, ensuring that the George Eliot Hospital has a safe and secure future, and building on our recent successes in the local economy. It will be business as usual in North Warwickshire & Bedworth for Team Dan.
“This has by no means been an easy decision, and I owe a great debt of gratitude to my parliamentary and constituency staff who have worked so tirelessly for the last four years on behalf of local people. I would also like to thank all of the local Conservative Party volunteers and councillors. Without their support, successfully overturning 18 years of Labour incumbency to return a Conservative MP with a significantly above average swing would simply not have been possible. My Conservative successor is extremely fortunate to inherit such a dedicated and experienced team. I will of course work closely with everyone to ensure a smooth handover and the best chance of success in 2015.”
