William Betts (died 1738) of Epsom, Surrey was a British merchant, financier and Whig politician who sat in the House of Commons between 1710 and 1730.
[1] Betts was invited by local Whigs to stand for parliament at Weymouth and Melcombe Regis, but his journey went through some challenges.
[1] Betts was returned for Weymouth at the 1715 general election and this time kept the seat for a whole parliament, sitting on the Dodington interest.
In 1730, the House considered a petition from Knox Ward claiming that Betts's election should be declared void on technical grounds.
Betts was by this time infirm and unable to attend the House and declared the electors should be given an opportunity to make another choice.
