MARTIN McGuinness is not having a good week. Much as he might wish it to, his IRA past simply refuses to go away.
And he doesn't like it.
He looked rattled when David Kelly, the courageous son of an IRA victim, first confronted him on the campaign trail.
But he was clearly outraged when Miriam O'Callaghan asked him how he squared his religion with the murders perpetrated by the IRA.
Maybe Mr McGuinness expected another soft ride from RTE, and one could hardly blame him judging the treatment Sinn Fein/IRA frequently get from the national broadcaster.
Miriam O'Callaghan posed a brilliant and appropriate question. And we all got a chance to see Mr McGuinness's true colours.
