Thank you for your support. My wife and I will have to get down to this next tax year and your question was a timely reminder!
Gov UK web site has the following gem which seems to contradict my answer viz:
'6 Available to spouses/ civil partners born after 5 April 1935. This allowance is 10% of the personal allowance for those born after 5 April 1938. It allows a spouse or civil partner who is not liable to income tax above the basic rate to transfer this amount of their personal allowance to their spouse/ civil partner. The recipient must not be liable to tax above the basic rate. The recipient is eligible to a tax reduction of 20% of the transferred amount.'
It says this is available in 15/16 tax year, but I have my doubts.
