As soon as news of Edward III's death, on 21 June 1377, reached the city, an influential deputation was sent to the young prince
Richard II and
Joan of Kent his mother. Philipot acted as spokesman assuring him of the loyalty of the city, and begged him to reconcile them with the Duke of Lancaster. The triumph of the principles of the
Good Parliament in the first parliament of the new reign was marked by the appointment in October 1377 of Philipot and
Walworth, at the request of the commons, to be treasurers of the moneys granted for the war with France. They and other London merchants lent the king 10,000
l. on the security of three
crowns and other
royal jewels. In 1378 Philipot fitted out at his own expense a small anti piracy naval squadron and captured the son of the pirate John Mercer which made him popular with the public. This very popularity made him unpopular with the nobles around John of Gaunt with
Hugh Stafford, one of the Lords liaising with the Commons in the
1378 Parliament attempted to
censure Philipot for mobilising a fleet without Crown approval - although Philipot replied that if the nobles had not left the country exposed to invasion he would never have interfered. At the height of his popularity he was chosen mayor for 1378–9, and filled the office with his usual activity and generosity. He had the city ditch cleaned out, levying a rate of fivepence per household for the purpose, and enforced order and justice so admirably that his measures were taken as a precedent nearly forty years later.
Lord Beauchamp of Bletsho in December 1379 appointed Philipot one of his
executors, bequeathing him 'my great cup gilt which the
King of Navarre gave me'. In the year after his mayoralty he earned the effusive gratitude of the city by defraying the cost of one of two stone towers, sixty feet high, built below
London Bridge, between which a
chain was suspended across the river to assure the safety of the city and shipping against possible French attacks. He was a member of the commission appointed in March of that year, at the request of the Commons, to inquire how far the heavy taxation could be lightened by greater economy in administration. He may have sat in this parliament, but the London writs are wanting. In the summer he provided
ships for the
Earl of Buckingham's expedition to
Brittany; and when the delay in starting forced many to pledge their armour, Philipot, as the
St. Albans chronicler heard from his own lips, redeemed no fewer than a thousand
jacks. It was to him that the intercepted correspondence of Sir
Ralph Ferrers with the French was brought, and Ferrers being with John of Gaunt in the
north, Philipot journeyed thither and saw him safely interned in
Durham Castle.} 's
Chronicles, At the crisis of the
Peasants' Revolt, in June 1381, Philipot came with Mayor
Walworth to the young King Richard's assistance, and Walworth having slain
Tyler in
Smithfield, he and four other aldermen were knighted with Walworth on the spot. He was granted an
augmentation of his coat-armour; and it may have been now that Richard gave him an estate of 40
l. a year. In November he again represented London in parliament. Filling the same position in the May parliament of the next year, Philipot was put on a committee of merchants to consider the proposed loan for the King's expedition to France, and was appointed a 'receiver and guardian' of the
tonnage and poundage appropriated to the keeping of the sea. But
John of Northampton, who was now mayor and busy depressing the influence of the greater companies, had him deposed from his office of alderman. In the spring and summer of 1383 Philipot carried out the transport arrangements for
Bishop Spencer and his
crusaders, and sat for London in the October parliament. == Death and legacy ==
