Re: Ha
A very quick internet search brought up a Guardian article from 18 October 2017, referring to the Prime Minster's claim that No deal is better than a bad deal.
It would be reasonable to expect therefore that the government has been making no deal preparations for at least 17 months.
Instead, it seems that they started about 5 months ago.
Lack of no deal preparation = fault of government (Prime Minister) seems a fair assessment.
