Regarding ISA's
From the HMRC
https://www.gov.uk/guidance/stocks-and-shares-investments-for-isa-managers#recognised-stock-exchanges
“Changes to investments held in a stocks and shares ISA”.
The most common examples of a change to an investment are:
takeovers
demergers
capital reorganizations (other than a rights issue or bonus issue)
rights issues
bonus issues
Investors may take up any offer to shareholders in respect of investments held in a stocks and shares ISA. Whether the resulting investments can be held in the ISA will depend on whether they are qualifying investments.
Where the new investments are qualifying investments, they can remain in a stocks and shares ISA.
Where the new investments are not qualifying investments, managers must, within 30 calendar days of the date on which they became non-qualifying investments, either:
sell them (in which case the proceeds can remain in the stocks and shares ISA)
transfer them to the investor to be held outside the ISA.
Complex reorganisations often involve more than just the issue of one set of new investments. There could, for example, be a bonus issue of shares, which are replaced in turn by other shares, which are then sold, or converted to other investments. If the intermediate investments are not qualifying investments for a stocks and shares ISA then, strictly, the final investments, or cash proceeds, cannot be held in a stocks and shares ISA even if the final investments themselves are eligible.
However, where ineligible investments are issued as an intermediate stage, and those investments are short-lived, or are automatically replaced by cash, HMRC will consider whether it is possible to look through the intermediate stages and apply the guidance on qualifying investments to the initial and final investments alone. If a reorganization involves intermediate ineligible investments managers should submit full details to savings.audit@hmrc.gsi.gov.uk, and if possible well before the planned reorganization date.
Where there are income and capital options available to an ISA investor, the ISA manager can select the income option (whether by choice or default) if any resulting (non-qualifying) deferred shares will be either cancelled or purchased for a negligible amount at some stage in the future (albeit not within the usual 30 days).
So to me there seems to be some leeway there. (Though I may be wrong)
