BBC TV is running a series of dramas under the theme of "Back to the 80s" at the moment. Last night, we had Abi Morgan’s Royal Wedding, a play set in a Welsh village on the day of Charles and Di’s wedding in 1981. It was superbly observed – even the colours were those of 1980s TV; too warm and sickly. The events at the village street party were intercut with footage from the actual TV coverage of the royal wedding with toe-curling results. Clearly, Charles was an idiot even back then and he hasn’t improved with age. Presiding over it all, like the ghost at the banquet, was the spirit of Thatcher, setting in motion the changes that would change British society forever.
