Paul di RestaPaul di Resta is set to finally be announced as a Formula 1 driver for Force India later this week, with his team scheduled to end weeks of speculation about its 2011 lineup.

Although di Resta is understood to have had a deal agreed with the team for some time, the British-based squad has stalled on making an announcement about its plans while it resolved contractual issues with Vitantonio Liuzzi. The silence from the team on that matter is expected to end on Wednesday, however, with the team having announced that it will hold a press conference about its 2011 plans.

Di Resta's promotion comes after the Scotsman impressed Force India during 2010 when he fulfilled Friday testing duties for the squad at a selection of grands prix. He was able to do that alongside his commitments with Mercedes-Benz in the DTM, where he ended the campaign as champion.

Liuzzi had a contract to race for Force India for 2011, but it appears that he and the team will part ways after a sometimes difficult season last year.
