I'm hoping someone on here can help me remember who/what this was.
Maybe 10 years ago, when Downton was still on but other than that I'm vague about the timings, there was a tv show on which had an actress in who looked uncannily like Joanna Froggatt. I googled her to find out if they were related and I'm fairly sure it directed me to a Mumsnet thread (though could have been digital spy/long forgotten alternative forum) of people discussing how alike they were.
When I strained my brain I thought perhaps the show was the syndicate s1 or 2 but I'm not at all confident about that so don't let that sway you!
Any thoughts?
