Honestly i couldn't say how much it should go up by I'm not an economist, but i do remember similar foretellings of doom and cries of think of the small business's when the minimum wage was first introduced. From my layman's point of view i would think business's small and large alike would welcome a rise in the minimum wage, after all if every working person now has more money that means they have more of it to spend. Instead of having just enough to pay the bills and all the other necessities, they now have enough to treat themselves to a morning cup of coffee on the way to work each day. By keeping wages low in effect you exclude a (large) proportion of the population from being able to afford anything but the bare necessities. Hey it's HMRC that lumps both terms into one pool, not me. It's way to early in the morning for me to go looking for a break down, if one even exists.
