The inclusion of Westwood and Clarke at St-Nom-la-Breteche near Paris was confirmed by their manager, Andrew ’Chubby’ Chandler.

McIlroy is missing the event as he indicated he needed two weeks  rest ahead of 12 weeks ’on the road’ with the Seve Trophy taking place during his break.

Westwood is currently ranked second on the qualifying table that  ends this Sunday at the close of the Swiss event.

It will be Westwood’s fourth appearance in the now biannual event but a first since 2003.

Clarke will forgo commitments at Archerfield in Scotland on September 18th, and the final day of the Vivendi, to also take his place in Paul McGinley’s Great Britian and Ireland team.

Clarke was concerned in breaking promises to be present to greet  Archerfield to guests ahead of a two-day charity fund raiser starting Monday and the day after the final round of the French event.

However Chandler indicated: “I know Darren was worried about breaking promises but we’ve organised a private jet straight from France to Edinburgh after the Vivendi, so he shouldn’t be too late for the Sunday evening function at Archerfield.” 

Clarke currently heads the second of two Seve Trophy qualifying tables but hasn’t represented GBR & IRL in the 10-man team’s event since 2002.

As well, it’s believed World No. 18 Paul Casey will make himself  available given he was cut last week from the FedEx Cup series.

He indicated following the recent PGA Championship in Atlanta not only a desire to compete but also to be on hand to honour Ballesteros’ memory.

Casey is lying fourth behind Clarke on the points table and should be assured of automatic selection.

The inclusion of three Ryder Cup stars in the Seve Trophy is also a big lift for European Ryder Cup captain, Jose Maria Olazabal  who had chosen McGinley and Continental Captain, Jean Van de Velde for the event.

Olazabal revealed he had written a letter some two weeks ago to all 10 current qualifiers, along with those on the fringe of selection, asking them to compete.

He said: “I wrote to all the players who look like qualifying asking them if they would consider playing not only because we need  them competing but also as this year it’s very much a tribute to Seve.

“So you will hear some good news in a couple of days.”
