Question about Lie derivative of connection [closed]

This is from Hughston and Tod, Ex 8.5. Please give me an idea how to start with this.

If $$\mathcal{L}_V g_{ij} = 2\phi g_{ij}$$ then prove that $$\mathcal{L}_V\Gamma^{i}_{jk} = \phi_{,j}\delta^{i}_{k} + \phi_{,k}\delta^{i}_{j} - g_{jk}\phi^{,i}.$$

I was thinking we could expand the connection in terms of the metric and then use Liebniz but I don't think the Lie derivative would commute past the derivative on the metric.
