According to the MoT history of the vehicle, this car is out of MoT. That's the bad news. The good news is that the car is at least on the DVLA system so you can trace old MoTs. If the car is yours and you've got a history file with it, then it's worth writing to previous owners (if you have their addresses) to find out more about the vehicle. You could also try contacting the MG Owners' Club and MG Enthusiasts club to see if it is known to them. Tracing a classic's history is a long and labour-intensive task that doesn't often yield great rewards - good luck with your search.
