Tim Yeo said in a statement today:
It has been a privilege to serve as MP for South Suffolk since 1983. I will continue to work for all my constituents until the General Election next year.
I am immensely grateful to all those Conservative Party members who voted for me to continue as their MP. I now ask them all to campaign for my successor with the same loyalty and dedication they have shown to me.
I will give my full and unqualified support to whoever is chosen as the candidate here in South Suffolk. I wish him or her every success.
