The Crimewatch Roadshow presenter told Press Association that dyspraxia is "kind of like dyslexia with your hands", explaining that he struggled in school when he was unable to do activities that his classmates could with ease.
Signs of dyspraxia may be present from an early age, with possible symptoms including poor co-ordination skills and untidy handwriting.
So what is dyspraxia, what are the symptoms and how common is it? Here's everything you need to know:
What is it?
Dyspraxia is a form of developmental co-ordination disorder (DCD), the Dyspraxia Foundation states.
The disorder can affect fine motor skills – the co-ordination of small muscles, such as the hands and fingers – and gross motor skills – the co-ordination of large muscles, such as the arms, legs and torso.
The condition may also impact a person's articulation when speaking.
While the terms dyspraxia and DCD are sometimes used interchangeably, they don't always refer to the same condition when used.
The NHS explains that the term "DCD" is preferred by the majority of healthcare professionals, as the term "dyspraxia" may have "several meanings".
"For example, dyspraxia can be used to describe movement difficulties that occur later in life as a result of damage to the brain, such as from a stroke or head injury," the NHS adds.
What are the symptoms?
Signs of dyspraxia may become evident from a young age in infants and children.
These symptoms include difficulty playing with toys or taking part in games that involve co-ordination skills, trouble using cutlery, untidy handwriting and an inability to do tasks such as doing up buttons or tying shoelaces, the NHS states.
Other symptoms may include falling over frequently and dropping objects.
However, the NHS points out that these signs may not necessarily by indicative of dyspraxia.

What are the causes?
While there is no confirmed cause of dyspraxia, there are factors that may put a child at greater risk of developing the disorder.
These include being born prematurely, weighing a below-average weight at birth, having relatives who had DCD or having a mother who drank alcohol or consumed illegal drugs during pregnancy, the NHS outlines.
How common is it?
Dyspraxia is more likely to affect boys than girls, states learning and attention issue organisation Understood.
It is believed to affect 10 per cent of the population, the Mental Health Foundation outlines, while two per cent are estimated to be severely affected by the condition.
How is it treated?
While children who have been diagnosed with dyspraxia may "grow out" of their symptoms, the NHS states, treatment may prove beneficial in the long run.
A paediatric occupational therapist may help a child with dyspraxia learn how carry out tasks such as handling cutlery, tying their shoelaces and writing.
Other health professionals that may benefit a child living with dyspraxia may include a paediatrician, a clinical psychologist and an educational psychologist.
