Cart with broken handle (needs welding back on) (Tattenhoe MK4)

Wondering if anyone can repair this to get more use out of it? This was my first trusty allotment cart - the front wheels are a bit wonky but it still moves ok, but the last straw was the handle breaking off. It's just balancing in the pic and can't actually be used to pull the cart; it needs welding back on at the bottom or some sort of attachment solution (I managed with rope for a while but steering was a challenge). The cart does fold up to store slightly smaller, I just forgot to get a pic of that.
