Walnut Orb weaver - (Nuctenea umbratica) found in the crevice between the tree and some loose bark. Apparently it is the second most venomous UK spider and is capable of biting humans causing itchiness and a burning sensation followed by a red patch with white lumps; some people have compared their bite to an electric shock. Thankfully these spiders are shy and unlikely to bite humans unless provoked. - I have no intentions of getting any closer than a camera lens away.
