He has sent out a statement to Conservative Party members in his constituency:
Message from Andrew.
15th May 2009
I wanted you to know immediately that this morning I resigned as David Cameron’s Senior Parliamentary and Political Adviser.
As you can imagine I have been working very closely with David over the expenses issue, and particularly his excellent tough stance, which has gained such approval this week.
Along with senior Shadow Cabinet members, I was among the first to submit my claims and receipts to internal Party examination. This morning, I was told that whilst I had acted on the advice of the Head of the Fees Office and been transparent in submitting annually my designated home and second home addresses, my arrangements would not necessarily pass David’s reasonableness test.
Consequently in a very early morning conversation with David, I submitted my resignation, which I thought was the right way forward.
I am sorry that we have all become embroiled in this expenses row, particularly as I was following advice. I am now traveling up to the Constituency to see as many of you as possible, and will of course be fulfilling engagements tomorrow and on Saturday, as well as campaigning for the European elections.
I have decided to call a public meeting in the Constituency on Friday, 22nd May, so that any constituents who have concerns can put them to me. I will let you have details as soon as this is arranged.
UPDATE : According to numbers collected by Bloomberg, MacKay and his wife Julie Kirkbride have claimed £282,731 since 2001. So that is £141,000 worth of over-claiming. No wonder why Cameron sacked him at sunrise this morning. This is straight forward looting.
