Incident at Tate Modern Art Gallery...

15 years minimum. He’s in Broadmoor so chances are he will never get out.

Although sentenced to 15 years in prison he’s in Broadmoor, a high security psychiatric hospital and is presumably likely to be detained under the MHA, probably a section 37/41 hospital order. He will in all likelihood be detained for much longer than his sentence and potentially for his whole life.
