Walter inherited several manors in Warwickshire, but resided mainly at Wimbledon, where his grandfather had acquired property by marriage.
When the Lords refused to proceed against Neile, on 1 June Walter demanded such an address from the Commons ‘as it might be a volley of great cannons in the king’s ears’.
It is not known whether Walter stood for the 1621 Parliament. In 1624 he unsuccessfully contested a seat at Stafford with Richard Dyott, a known Arminian. On his petition Dyott’s election was declared void, but Walter does not seem to have stood at the second election, or indeed at the general election to Charles I’s first Parliament.
The outcome of this speech was that Walter was silenced during the rest of the Parliament, although the only direct evidence we have of royal displeasure is that he was dismissed from the commission of the peace.
In 1628 Walter was elected at Lichfield, where he may have had a kinsman on the corporation.
On 23 Dec. 1628 Walter offered £200 to Thingdon school in discharge of £166 13s. 4d. held in trust by his father.
