A spokesperson for the 26-year-old Scot confirmed yesterday Di Resta and Hamilton had parted company after two years together.
With the announcement coming ahead of the British Grand Prix, and at a time when Di Resta will be looking at his options for next season, the announcement could not have come at a worse time for the Sahara Force India driver.
Di Resta was initially tight-lipped on the matter when asked as he said: “It’s been confirmed we’re no longer working together, and that is the situation at the moment.”
In terms of being managerless for the foreseeable future, and with an eye towards 2013, he added: “I’m just fully focused on my racing. At the end of the day it’s results that count for me and are what are going to drive me forward.
“I’ve had a good year up until now, and I aim to continue that progress. For now, the focus this weekend is to have a good race. It’s a big weekend for me with a lot of friends and family around, a lot of support. As one of the three Brits on the grid (Lewis Hamilton and Jenson Button) I’ve a feeling for what it is like to have a country behind you.”
