Robert Hammond, known as James, murdered Sian Hammond at their home in Primes Corner, Histon, near Cambridge, on 29 October last year.
The court heard Hammond had growing debts of more than £300,000 and had spent months lying and creating excuses to delay payments to HMRC and a financial company.
However, today (17 July), at Cambridge Crown Court a jury returned a unanimous guilty verdict on a charge of murder.
