Sloe Hairstreak?

As is so often the case for me, new territory here. It is a hairstreak but the choice seems to be Sloe, Ilex or False Ilex..
The pattenr seems to me to eliminate Ilex and the flase Ilex distribution mp does not look correct leaving one with Sloe Hairstreak, Plenty of sloes about is a good pointer too.
Do please tell me if I am wrong!
Edit: Further reflection and I am now leaning towards False Ilex!
Second edit: Actually with more photos taken the next day, I am back to Sloe.
