My Lords, there are arguments in both directions. Not only, as my noble friend said, did this country try it in the 1960s and then change back again three years later, but Portugal tried it in the 1990s and changed back again too. These are complex matters. The Prime Minister has said that there needs to be consensus before any change.
My Lords, when working on Wall Street I had to clear share offerings in five different time zones within the United States in 24 hours. Does the Minister agree that time zones are more appropriately determined by geography than by commerce?
I think that I would, my Lords. On the subject of trade, it seems likely that there could be benefits for some businesses that trade with European states particularly that are not in our time zone, and indeed with other parts of the world further east. There could also be some losers from the trade perspective. One of our most important EU trading partners, the Republic of Ireland, shares our time zone, of course, so a rigorous analysis of all the overall impacts would be needed before any conclusions could be formed.
