Bulbous

Prawny Wasp was back again today, getting annoyed as there wasn't any prawns in sight. One of my guests didn't like him constantly searching the garden table and I'm sad to say Prawny Wasp is no more :-(
It wasn't long after photographing this spider by the pond, that one of Prawny's friends started to have a go and I have no idea how he managed it, but it landed on my arm, climbed inside my t-shirt sleeve and stung me! I was gutted to see Prawny's demise, but after being stung I had a slightly different view!

Can anyone identify my spider?
