Dame Deborah James' charity T-shirt worn by Andy Murray’s wife at Wimbledon

Andy Murray's wife, Kim Murray, has shown her support to Dame Deborah James by wearing the charity T-shirt the bowel cancer campaigner has designed.

Ms Murray, 34, was attending the first day of Wimbledon and watched from the stands as her husband took on James Duckworth, with the mum-of-three donning a ‘Rebellious Hope’ T-shirt for the occasion.

Seated next to her mother-in-law, Judy Murray, she teamed the top with jeans and bracelets, and kept her long hair loose.

Dame Deborah, who was diagnosed with bowel cancer in 2016, revealed last month that she is now in end-of-life hospice care at home, surrounded by her loved ones.

Last month, she launched the £15 T-shirt in collaboration with fashion brand In The Style, with all the proceeds going to the BowelBabe fund.

The T-shirt has also been given royal approval with Sophie Countess of Wessex opting to add it to her wardrobe during a recent tour of Gibraltar.

Stepping out in Gibraltar, the mum-of-two switched her typically glamorous attire for the casual top with the inspiring slogan emblazoned across it.

Dame Deborah was thrilled with the royal support and shared a picture of the countess in the T-shirt to her Instagram stories.

"How great does the Countess of Wessex look in the @inthestyle Rebellious Hope t-shirt for the @bowelbabefund - thank you for the support Sophie! @theroyalfamily," she wrote.

The BowelBabe Fund for Cancer Research UK was set up by Dame Deborah and her family to help fund clinical trials and research into new treatments for cancer patients, all while raising awareness of bowel cancer.

In less than a week, The BowelBabe Fund raised more than £6m in donations, with funds continuing to grow.

As well as designing the charity T-shirt, Dame Deborah has also been working on her own collection with In The Style.

While the main collection isn’t ready yet, Dame Deborah revealed on Instagram that she had already worn one of the dresses when she met Prince William who personally delivered her damehood to her family home.

Last week the You, Me, And The Big C presenter urged big supermarket brands to include bowel cancer symptoms on toilet roll.

Her call for action on ITV's Lorraine comes after retailer Marks and Spencer announced plans to add information on signs of the disease to its packaging.

During an edition of the breakfast show, Dame Deborah appeared to congratulate her friend Cara Hoofe – who was diagnosed with bowel cancer at 32 – on successfully pitching the idea of putting symptoms on loo roll wrapping to her employer M&S, to which they agreed.

She then urged other retailers to follow M&S lead to help raise awareness about the symptoms of bowel cancer by putting them on toilet rolls.

"I think we should do a big shout out to other companies now saying, like, ‘Where's your signs and symptoms?" she said in a video message.

"Forget about the puppies — I’m bored of the puppies," she continued. "We need actual information signposted on those loo rolls. So I'm hoping that lots of other big brands will now go, ‘Yeah, hang on. This makes massive sense. This is what we need to be doing.’

"So I can't wait to see that happen. And a massive, massive well done to you,” she concluded her message.

Following the powerful call for action, Andrex revealed it will display the common signs of the disease – the fourth most common cancer and second biggest cancer killer in the UK – on as many as 29 million packs.

Almost half of adults in the UK can’t name a single symptom of bowel cancer, which is the general term for cancer that begins in the large bowel. Knowing the symptoms, and acting on them, means that it can be diagnosed earlier when it is more treatable and curable. But fewer than 40% of people are diagnosed at the earliest stages.
