Royal Borough councillor Peter Lawless has resigned from the Conservative group after pleading guilty to benefit fraud offences on Friday.
The representative for Eton Wick was given a two-year conditional discharge after he admitted three charges of failing to notify a change in circumstances which he knew affected his entitlement to benefit at Slough Magistrates Court.
He received £4,839.11 in housing benefit overpayments between May 16, 2011 and January 6, 2014.
He did not declare his council members' allowance, through which he earned £19,590.48 in that time.
Conservative Group Leader, Cllr David Burbage said: “Cllr Lawless had already been suspended by the Conservative Group after he had been charged with the offences, pending further action.
"Following the court case, I have accepted his immediate resignation from the Conservative Group.
"As he is no longer a Group member, there is no further action we can take."
The 62-year-old, of Eton Wick Road, now ceases to take the Conservative whip but remains as a councillor at the time of writing.
