Sara Davies admits Strictly co-star Robert Webb was 'struggling' during last ...

Sara Davies has revealed she could see Robert Webb was 'struggling' during last week's episode of Strictly Come Dancing.

It comes after the comedian, 49, withdrew from the competition after seeking an 'urgent consolidation' with the specialist overseeing his recovery from heart surgery.

Partnered with professional dancer Dianne Buswell, he admitted he wasn't at the right stage of his recovery to cope with the demands of the show.

His fellow contestant Sara - best known as an investor on BBC's Dragon's Den - has revealed she noticed Robert was finding it difficult to keep up with the pace.

The businesswoman, 37, partnered with Aljaž Škorjanec, told Radio Times: 'He's such a big personality Robert.

'They're the couple who are just in front of us, so for me, the most exciting moment is that five minutes before we get ready to go out and I feel like I shared that with Robert every week.

She added: 'I got to know Diane as well and the joke last week was that she got my blonde hair, and I got her red hair. But I could see that Robert was really kind of struggling. I watched him last week and he was struggling.'

The television personality admitted the Peep Show star must have been 'devastated' and likely continued for as long as he did so not to let his choreographer down. 

'For him to take that decision must have been so difficult because it's not like you can say, "I want to kind of have a few weeks off and then see if I feel any better." It's a once in a lifetime opportunity, so I know how devastated he'd have been to pull out.'

Robert announced his decision on Wednesday night, admitting he had 'bitten off more than he could chew', having an ongoing heart condition and two years after undergoing open-heart surgery.

His pro partner Dianne will also be leaving the competition.

Robert said of the decision: 'I'm extremely sorry to have to announce that I'm withdrawing from Strictly Come Dancing due to ill health.

'Two years ago I had open heart surgery and although I believed I was fit enough to take on Strictly and its demanding schedule, it became clear that I had bitten off way more than I could chew for this stage in my recovery.

'I had begun to feel symptoms that led me to seek an urgent consultation with my heart specialist, and it was her view that it would be better for the sake of my health to step back from the show.'

He went on: 'I'm proud of the three dances that Dianne Buswell and I managed to perform and deeply regret having to let her down like this. I couldn't have wished for a more talented partner or more patient teacher, and it's a measure of Dianne's professionalism and kindness that I was able to get as far as I did.

'Thanks too to everyone at home who voted for us. It was always going to be a difficult mountain to climb (for one thing it's made of glitter so it's very skiddy) and I've been especially touched by the support from fellow heart patients.

'I think perhaps I was too eager to impress them. They will know that recovery doesn't always go in a straight line, and I hope they're not too disappointed that I ran into the limits of my resilience much sooner than I'd hoped.

'I leave knowing that Strictly viewers are in very safe hands and I'll be cheering for my brother and sister contestants all the way to Christmas.

'Despite this sad ending, it has been a genuine honour to be part of this huge, joyful and barking mad TV show. Long may it continue.'

Dianne added: 'As a massive fan of Robert's I was delighted to find out that he was joining the Strictly family. On top of this, to find out he was my partner was the icing on the cake.

'We made a great team, worked hard and had a good laugh along the way. I am so proud of the three amazing dances we produced.

'I know Robert had a lot more to give to the competition but his health of course comes first and I wish him a speedy recovery. I feel lucky to have danced with him and to call him a friend.'

Sarah James, Strictly Come Dancing Executive Producer, said: 'Although we are so sad that Robert has withdrawn from the show we completely understand and support his decision, health always comes first.

'Despite their Strictly journey coming to an end earlier than anyone would have hoped, Robert and Dianne really made their mark on the competition, with three unforgettable dances choreographed superbly by the brilliant Dianne.

'They have been a wonderful partnership and we'd like to thank them for the commitment, creativity and joy they brought to the show. Everyone involved in Strictly Come Dancing sends Robert their love and best wishes for his continued recovery.'

Strictly Come Dancing will continue this Saturday with 12 couples taking to the Ballroom floor to impress the judges and the voting public.

Robert spoke recently that he was left barely able to walk last year after the emergency surgery for his congenital heart defect.

The Peep Show star learned the condition was made worse from his ten-year battle with alcohol.

Speaking to The Sun, Robert told how he saw participating in the BBC series as the latest step on his road to recovery.

He said: 'When I first came out of hospital I could not walk to the end of the street without help. I couldn't even lift a kettle for four weeks.

'So gradually you build up again until you are doing longer and longer walks. Then seven months later the walks turn into runs —
