Rose Moore, who lives in Alicante, Spain, told Spanish ex-pat website The Olive Press that she has not seen or heard from her son since she voted Leave in the 2016 EU Referendum.
The 63-year-old told the website: “I still stand by my decision, no one has the right to tell me how to vote.”
She said her son, a graphic designer in London, could not understand her point of view and has yet to forgive her for playing a part in the UK’s divorce from the union.
The mum-of-two said the decision made her ‘sad’ – and that Brexit has turned her from a lifelong Labour vote to a Conservative supporter - something she said she ‘never thought would happen’.
She told the website she backs Prime Minister Boris Johnson to secure an 11th hour deal and added: “If we go on no deal, the EU will suffer. It may be spread over the poorer countries, but they will feel it.”
She added that the idea of a new referendum was ‘disgusting’ and a ‘bad idea’ and that she would fly back to vote Leave again.
The UK is scheduled to leave the EU on October 31.
