A vinter and ‘merchant’, Newton is not known to have exercised office within Worcester, in spite of representing the city in at least three Parliaments, two of them consecutive.
It would appear that Newton had business dealings in London, since during his last Parliament he was pardoned an outlawry he had incurred at Westminster for failing to answer a suit for debt brought by a grocer from the City.
Away from Parliament, Newton was among those who bound themselves in a recognizance for £200 in late April 1452, as a guarantee that two men from Worcester, a spurrier and a corviser, would come before the King and the council whenever the Crown commanded. Newton and a fellow surety, John Colman, went to Chancery in person on the following 4 May when the keeper of the rolls directed them to ensure that their fellow townsmen would appear within 15 days.
In early February 1457 the sheriff of Herefordshire, (Sir) John Skydemore*, was directed to take action against Humphrey Stafford and his associates, Newton included, for failing to meet the obligations placed upon them by the statute staple of 1449. Just over four weeks later, Skydemore returned that he had imprisoned Stafford at Hereford but had not found Newton or any of the other men, none of whom possessed any lands or goods within his bailiwick.
