So how much does #Brexit cost?

In a letter to a Labour MP (seen by the FT), Cabinet Office minister Baroness Lucy Neville-Rolfe admits, 

“It will depend greatly on how businesses adapt their business models & supply chains to integrate the new controls regimes. We estimate these new costs of the model at £330mn p.a [per annum] overall, across all EU imports,” 

Did I miss the big bus with this on the side?

Oh that's right, all those warnings about the costs of Brexit were 'project fear'!
