Insect and Spider Identification: Big red spider England, 3 by App

Hi, I found this big red spider in my garden (about the size of a 50p coin). It had huge eyes (or at least something that looked like eyes) and there were loads of little spiders around it too. Can someone tell me what spider this is and whether it is dangerous? I live in England so I am not used to seeing such big fat spiders. I have attached images for reference. Many thanks

Ps sorry that the images are not the best of quality, I was too scared to get too close.
