They were held separately in the notorious Evin jail and later charged with spying, which they deny.

Now they've been sentenced to 10 years in prison.

The British government says it's totally unjustifiable.

Ahead of the sentencing, the BBC's Anna Foster managed to speak to Lindsay Foreman by phone from inside the jail.

The couple had just sent a letter to the Iranian authorities complaining about their treatment.

It's a rollercoaster.

There's a pre-me, this situation.

I've been sort of trying to work out what I feel.

The shock is what I would have felt, but now I'm not shocked by anything that happened here.

The physical reaction was, like I said, what I would be used to is, you know, the pit of my stomach and my mouth went dry and disbelief, really.

But then I'm surrounded by people who are in

worse situations who've had to live this their entire life so some way i feel lucky that a i've had the life i've had up until this point and hopefully one day for me will end and i will come out of this situation um a wiser person

What effect is this having, Lindsay, on your physical health and on your mental health as well?

Well, physically, I've been doing yoga since solitary confinement.

So it has been my absolute saviour, probably physically and mentally.

I was running around in circles, trying to do 5K.

I'm passionate about parkrun, love doing 5K runs and was attempting to maintain that.

But it's incredibly difficult in a very small yard, I think.

And I've, I suppose, resigned myself to the fact that my physical health might not be what it was before I came in, but that I can regain it when I leave.

And mentally, it's like an endurance test for the mind.
