The Ashton-under-Lyne MP announced the birth of her first grandchild in an early-morning tweet in which she gave herself the new nickname Grangela.

Earlier this year, she recalled her experience of being a teenage mother on a council estate, saying the birth of her son “actually saved me from where I could have been because I had a little person to look after - I wanted to prove that I could be a good mum and somebody was finally going to love me as much as I deserved to be loved, and that's what pregnancy was for me”.
