Margaret was questioned by William Fitzwilliam, and Thomas Goodrich, Bishop of Ely. As part of the evidence for the Bill of Attainder, Thomas Cromwell produced a tunic bearing the Five Wounds of Christ, symbolising Margaret's support for Roman Catholicism and the rule of her son Reginald and the king's Catholic daughter Mary. In May 1539, Henry, Margaret, Exeter and others were attainted and sentenced to death. In January 1539, Geoffrey Pole received a pardon, while Montagu and Exeter were tried and executed for treason.

Montagu, Exeter, and the aged Countess of Salisbury, last of the Plantagenets, were all arrested in November 1538, on charges of treason, They were imprisoned in the Tower and Reginald Pole was attainted. When questioned, Sir Geoffrey revealed that his eldest brother, Henry Pole, Lord Montagu, and his cousin, Henry Courtenay, Marquess of Exeter, had been party to his correspondence with Reginald. His brother, Sir Geoffrey Pole, with whom he had been in correspondence, was arrested in August 1538. The king, ruthless when crossed and unable to strike out at Pole, exacted a terrible revenge on his family. Henry, incensed, wrote to the Countess of Salisbury, who sent a reproving letter to her son. To add insult to injury, he also urged the monarchs of Europe to depose Henry. Reginald sent Henry a copy of his treatise 'Pro ecclesiasticae unitatis defensione' which strongly denounced the king's policies, his position on the marriage of a brother's wife, and the Royal Supremacy. Pole, however, would not support the king in this aim and went into self-imposed exile in 1532. He returned home in July 1526, the king, eager to divorce his first wife, Catherine of Aragon to marry Anne Boleyn, offered him the Archbishopric of York or the Diocese of Winchester if he would support his divorce. In 1521 Pole went to the University of Padua, from where he corresponded with the humanist Erasmus, his studies there were partly paid for by Henry VIII. Of slender build and medium height, Pole had light brown hair and was said to have a gentle expression. In February 1518, He was granted the deanery of Wimborne Minster, Dorset by his second cousin, King Henry VIII after which he became Prebendary of Salisbury and Dean of Exeter in 1527. Reginald was educated at at the school of the Charterhouse at Sheen and at Magdalen College, Oxford from where he graduated with a BA on 27 June 1515. Edith was the half-sister of Lady Margaret Beaufort, mother of King Henry VII. His father Richard Pole was of Welsh descent, the son of Sir Geoffrey Pole and Edith St John. The Countess was a first cousin of the Queen, Elizabeth of York, she was the daughter of George, Duke of Clarence, and Isabel Neville, making her son a great-grandson of Richard Neville, 'Warwick the King Maker' and Richard Plantagenet, Duke of York.

He was the second son of Sir Richard Pole and Margaret Pole, Countess of Salisbury. Reginald Pole was born on 12 March 1500 at Stourton Castle, in Staffordshire.
