Given that the unanimous vote by MPs today was not binding, what are the chances of Sir Philip Green being stripped of his knighthood?

The future of his honour is in the hands of a secretive panel who sit on what's called the Honours Forfeiture Committee.

They do not tell us if they are going to examine Sir Philip's knighthood, nor when they might consider his knighthood.

But the vote by so many Parliamentarians today must surely have a bearing on their thinking.

The Honours Forfeiture Committee only have two clear criteria upon which to strip a person of their knighthood: a prison sentence of longer than 3 months; or being struck off by a professional authority (like a doctor).

So in this case, it will be a matter of judgement.

The most recent case of a knighthood-stripping was in 2012 when Sir Fred Goodwin became plain old Fred Goodwin for leading RBS to the edge of the cliff before the financial crisis.

Today, MP after MP lined up today to criticise Sir Philip over the way he ran BHS, then subsequently sold it.

I counted around two dozen members who made speeches or contributions over a three hour debate.

But the decision on Sir Philip's knighthood is not theirs to make.

Nor is it for the 11,000 former staff of BHS to make - although some of them told us today they agreed wholeheartedly with the view of MPs.

Instead, the decision now rests with a secret committee.
