Saw the end tonight. £75k and £250k the last two boxes. Offer by umpire of £125k turned down. Then the umpire offers the winner the option to swap the box she originally chose. Before I disclose the result what would people here have done? Purely on the basis that it was unlikely that she chose the £250k box at the outset and the other box had been left by a series of eliminations I would have swapped. She stuck with her original box.
