Cecil was displeased with the arrangement, given his daughter's age compared to de Vere's, and had entertained the idea of marrying her to the Earl of Rutland instead.
In addition, Cecil had been elevated to the peerage as Lord Burghley in February 1571, thus elevating his daughter's rank, so the negotiations were cancelled.
Anne had been pledged to Philip Sidney two years earlier, but after a year of negotiations Sidney's father, Sir Henry, was declining in the Queen's favour and Cecil suspected financial difficulties.
In the summer of 1571, de Vere declared an interest in Cecil's 14 year-old daughter, Anne, and received the queen's consent to the marriage.
