Will be interesting. For starters, I don't see the need for a Racing Minister at all...there isn't a M for rugby, netball, motor racing, etc. And, reportedly, a former Minister, Annette King, apparently said that there was nothing she could do, whatever she might have wished, as there was never a consensus, just a medley of factions all pushing their own barrows.
What is likely to change? However able Grant may or may not be, he is loaded with enough work to have racing sitting right at the bottom of the pile - as it should be - and I don't see anyone who has industry clout, is respected by all, and is logical and far-seeing enough to engage with him and actually achieve anything.
