I believe all high octane fuels have 5% ethanol in them.
From the Shell UK website:

"....in the UK, Shell regular unleaded and Shell V-Power unleaded are likely to contain some ethanol, but it will not be present at more than 5% (in accordance with current UK specification requirements)"

I use Tesco 99 in the Morgan and the AMG.
No issues.
