Fiona Shaw cut a casual figure as she went for an evening stroll with her economist wife Sonali Deraniyagala in London this week.

The 60-year-old Killing Eve actress sported a grey top and matching tracksuit bottoms along with a pair of trainers for her day out with her spouse, 56.

Their casual outing comes as Fiona reveals that it was a ‘shock’ to discover that she was gay after years of happily dating men, which left her ‘full of self-hatred’.

The actress, who has previously had a relationship with actress Saffron Burrows, said that she has now learnt that she is ‘not in control’ about certain aspects of her life.

‘I wasn’t in any way gay until I was. One goes on developing. As a teenager, I was very modest in my romantic life,’ she told the Big Issue.

‘I had this wonderful boyfriend, then another, then later I became gay. It was a shock. I was full of self-hatred and thought I would come back into the fold shortly. But I just didn’t.’

Out and about: The couple looked in high spirits as they laughed and chatted with each other after going to the gym

Fiona said that she would now tell her younger self ‘you must be very gentle on yourself’ and that ‘you are not in control of those aspects of yourself and you mustn’t try to be’.

The Harry Potter actress went public with her romance with Dr Deraniyagala earlier this year, after the pair were introduced by mutual friends.

She had read Dr Deraniyagala’s award-winning memoir, Wave, about the tragic loss of her entire family in the 2004 Boxing Day Tsunami and asked to meet her.

‘I married and that calms you down. I didn’t really have a domestic life because I was always working. But I do have one now, which I love,’ said Fiona earlier this year.

Fiona, who plays Carolyn Martens, head of the Russia Section at MI6 in the show, is also known to film audiences for her role as Aunt Petunia in the Harry Potter series.

The actress' wife Sonali is an economist who previously told of her tragedy at losing her husband and two sons in the 2004 Indian Ocean earthquake and tsunami.

Dr Deraniyagala was on a Christmas break in her native Sri Lanka along with her economist husband Stephen Lissenburgh, their sons, Vikram, five, Nikhil, seven, and her parents Gemini and Edward.

Story: The devastating loss sent Dr Deraniyagala into years of depression which she wrote about in Wave, a moving memoir she wrote in 2013

They were staying at the Yala Safari Beach Hotel in the south of the country, which was directly in the path of the tsunami.

As they spotted impending giant waves surging towards them, Dr Deraniyagla and her husband grabbed their children, rushed out of the hotel and attempted to escape in a jeep, not even having time to collect her parents from a nearby room.

As the family tried to race away they became submerged in a 30 feet wall of water.

'I think he (Stephen) saw the wave when it was rising and when it was coming at us,' she recalled the last moment she saw her husband alive.

'The last I saw of Steve was that look on his face where he looked completely aghast, seeing something that I couldn't see...

Praise: The book won a host of awards and was described by some critics as one of the best ever written about coping with tragedy and family loss

'But I couldn't turn back; I didn't have time to turn back and look ... because that's when the jeep turned over and we were all dispersed.'

Tragically, she was the only one who survived. The bodies of Vikram and her parents were found several days after the tsunami while Stephen and Nikhil were discovered months later in a mass grave and were identified through DNA tests.

The devastating loss sent Dr Deraniyagala into years of depression during which time she contemplated suicide and also abused alcohol and prescription pills, as she confessed in Wave, a moving memoir she wrote in 2013 about her struggle to come to terms with what had happened.

After months of living in near isolation in Colombo, Dr Deraniyagala moved to New York where she was treated by eminent psychotherapist Mark Epstein who specialises in the area of traumatic experiences.

Memoir: The book also contains extensive sections of the happy family life Dr Deraniyagala enjoyed

It was he who initially suggested that she start writing down her thoughts, which formed the basis of her award-winning memoir.

'It was so painful to write,' she once said. 'The trauma of it, the joy of our life, all of it. You can't have one without the other.'

The book won a host of awards and was described by some critics as one of the best ever written about coping with tragedy and family loss.

In addition to her heartache, it also contains extensive sections of the happy family life Dr Deraniyagala enjoyed, from her son's obsession with cricket and wildlife to spending moments with her husband and their holidays in Sri Lanka.

It so moved Fiona, who read it in New York while starring in the Broadway production 'The Testament of Mary' in 2013 that she asked to meet its author and the two were introduced through mutual friends, hitting it off straight away.

The couple now have homes in Islington, north London and Chelsea, in New York's Manhattan district.
