Now, does this mean he has resigned because he's refusing to pay the money back? Has the whip been withdrawn? Guess we'll have to wait for details.
Also now on Sky News. The new "scrutiny panel" met for the first time today, and Camero told Sky that "if [MPs] do not co-operate they will not be able to be Conservative MPs." Wonder if this is what has happened to Mackay?
UPDATE: Apparently Mackay, and his MP wife, Julie Kirkbride, both claimed full second home allowances on two separate properties. Sky have written that,
"The Press Association says Mr MacKay, who is married to Bromsgrove Tory MP Julie Kirkbride, claimed the full second-home allowance for interest on their joint mortgage for a London home until April this year.Coining it basically.
But at the same time his wife also claimed the full annual sum for mortgage interest on a constituency home - meaning they appeared to have two second homes but no main home, sources said."
