Whether Walter was related to John le Clerk, who had represented Southampton in eight Parliaments of the fourteenth century, does not appear from the records, although he was evidently not descended from him directly.
Clerk first became involved in the affairs of the borough in January 1447, when he was among the merchants specially appointed by the mayor to appraise the goods of the recently-deceased Richard Thomas. Later in the year he was made water-bailiff,
That same year Clerk contracted with (Sir) Gervase Clifton*, the treasurer of Calais, to supply the garrison with victuals, but on 15 Nov. 1456 his letters of protection were revoked as he was tarrying at Westminster (perhaps fulfilling his final duties as sheriff), and had failed to carry out his commitments.
The late 1450s witnessed escalating feuds among the burgesses of Southampton. One such, initially arising during the mayoralty of Nicholas Holmehegge* in 1454-5, involved a quarrel with John Chapman of Shaftesbury, yeoman-porter to the duke of Somerset, over wrongs allegedly done him by the mayor and other town officers, which was not settled until Clerk’s mayoralty in November 1457. The steward then paid Chapman 33s. 4d. to put an end to the matter, and Chapman made a quitclaim to Holmehegge, Clerk and others, including John William*, ceasing his legal actions against them.
These lawsuits were still not resolved by September 1460, and evidently then played their part in provoking the disruption of the mayoral election at the guildhall in Southampton. Payn’s faction, supported by an armed mob, imposed their own candidate on the assembly, defeating those nominated by Gryme as the outgoing mayor. Clerk’s exclusion from power in Southampton was no doubt behind his decision to seek election to the Parliament summoned for 7 Oct. Clearly, his candidacy would not have been supported in a Southampton riven with disputes and now under the control of his enemies, although why he chose to stand for Chippenham in Wiltshire, a borough with which he had no known connexion, is less easy to explain. It may be, however, that his wife’s brother-in-law Hall, now returned for Salisbury, helped him to succeed at the hustings. Hall had his own reasons for seeking election to this particular Parliament, meeting in the aftermath of the Yorkist victory at Northampton, not least to clear his name on charges of treason. Both he and Clerk no doubt hoped that the privileges enjoyed by Members of the Commons would protect them, at least for a while, from further prosecution in the central courts. Process of Payn’s many suits against the two of them and Ingoldesby was continuing, and at the same time Payn was suing Clerk alone in the court of common pleas for a debt of £20. As a consequence, when Clerk arrived at Westminster to attend the Parliament as burgess for Chippenham he was arrested, imprisoned in the Counter and from thence removed to the Exchequer and committed to the Fleet, not only to answer for the £40 in which he was condemned to pay the Crown as a fine, but also for the 20 marks which he had been adjudged to pay Robert Basset in an action of trespass, and for the £20 due to Payn in an action of maintenance. He was outlawed for failing to answer Payn’s suit. This prompted ‘grete delaye’ at the start of business in the Parliament, as the Commons protested that they had always been entitled to ‘free commyng, goyng and . . . abidyng’, and that Clerk’s imprisonment was injurious to their ‘libertees and fredomes’. They requested his immediate release so he might attend Parliament daily ‘as his dute is to doo’. The Commons’ petition, having been ‘lecta, audita et plenius intellecta’, was granted by the King, saving always the rights of himself, Payn and Basset to have due justice after Parliament was dissolved.
Accordingly, after the Parliament ended and Edward IV replaced Henry VI Payn and Fleming resumed their actions against Clerk in the King’s bench. In July 1461 Clerk entered a recognizance at the staple of Westminster as bound to Payn in 50 marks, and as a consequence of his failure to pay on the appointed day a writ went out for his arrest a year later. He was committed to the Marshalsea prison, and only managed to obtain release at Easter 1463 after his wife Ellen persuaded Hall to pay 40 marks still due to Payn, and offer substantial sureties.
Some seven years after Clerk’s death, which occurred at an unknown date in the 12 months from March 1472,
