I have French shares held within my ISA wrapper with Interactive Investor ( II ). Dividends suffer French withholding tax. I understand that II does not reclaim tax withheld under the Tax Treaty. Am I able to reclaim the tax or should II be responsible?

Is there a current UK/France tax treaty to prescribe the rate of withholding tax on French dividends received in to a UK resident's ISA? My dividends are currently subjected to French Non-Treaty rate 25%.
