My mother received a letter with enclosed check of indicating winnings of $125, 000 from Mega Lottery conducted in the U.K. on July 27th, 2012 with a ticket serial number and winning number. There is an indication that the company who sent the letter tried "many unsuccessful attempts to contact you" regarding this winnings (no one ever tried to contact her prior to this letter). It indicates that this is her share of a $4M pot with 32 other random winners from the US, Canada, Mexico, and the U.K.
The enclosed check was in the amount of $2, 770 which was deducted from her winnings and enclosed to expedite the processing. It says the sole purpose of the check is for the payment of applicable government taxes on her big winnings. Also says government taxes cannot be deducted from the winning amount because of the insurance policy coverage. The letter goes on to say that the tax amount of $1, 770 must be paid directly to the tax agent.
