Thank you for the response, if the property is still classed in my Father's estate why would I be liable for any gains as the property due to GROB is his and not mine?
Why would my gifting my share to my Father be a capital gains disposal? Are saying that any gift you make you have to pay capital gains tax on it?
There is a a good article here which seems to infer that there is no CGT by removing someone from a Joint Tenancy:

To say I'm confused is an understatement - any help much appreciated
It sounds as though the property will be in his estate anyway so (as maths says) it may not be a problem.
This is primarily a CGT issue as you can't claim PPR on your share when the property is sold (and if your father died there would be no tax free uplift on your share). Equally, if you gift back your share, that will be a CGT disposal at market value so you may well have to pay CGT on your share.
