IN his letter to David Cameron, Mark Harper wrote: "Although I complied with the law at all times, I consider that as Immigration Minister, who is taking legislation through Parliament which will toughen up our immigration laws, I should hold myself to a higher standard than expected of others.
"I have also considered the impact on my Parliamentary colleagues, the Government and you. I have always believed that politics is a team game, not an individual sport. I have therefore decided that the right course is for me to return to the backbenches. I am sorry for any embarrassment caused.
"I am grateful for the opportunities you have given me since you became leader of the Conservative Party, first in opposition and then in government. I will continue to support you, the Conservative Party and this government in whatever way I can from the backbenches. I will also continue to serve my constituents in the Forest of Dean to the best of my ability."
