Sussex all-rounders Chris Jordan and and Luke Wright have been included in England one-day squads for the limited-overs leg of the Ashes tour in the new year.

Jordan has a chance to play in the five one-day internationals and Wright in three t20s scheduled for January and February.

Kevin Pietersen, James Anderson and Graeme Swann will take no part in either series.

All three are central to England's ongoing Test campaign down under.

Pietersen also seems sure to figure in future limited-overs engagements such as next year's ICC World Twenty20 and the 2015 World Cup, along with Anderson at the latter.

All were all absent, though, from the 15 and 16-man squads announced on Tuesday morning.

Test captain Alastair Cook will lead the ODI squad, with Stuart Broad once again in charge of the Twenty20 tourists.

England's Test coach Andy Flower explained the reasons for trimming the competitive workload for 33-year-old Pietersen and Anderson, who is two years younger.

Swann's omission is, conceivably, more a selection issue - with James Tredwell once again involved.

Flower said: ''This is going to be another month of tough cricket, and then a heavy schedule from the West Indies tour onwards.

''Straight after the Twenty20 World Cup, the Indian Premier League begins - and while that's on, the English season starts.

''Our players who play all three forms cannot play 12 months a year.

''Guys like Anderson and Pietersen are in their early 30s now; they are prize assets, and we need to look after them.''

The intention is to preserve and hone their skills for higher-profile assignments ahead.

Flower added: ''From a physical perspective, they're always dealing with various niggles - and sometimes they need to be taken out of competition.

''That is not for them just to rest - it's so we can maximise their skills when they do play.''

National selector Geoff Miller said: ''We have an important period of limited-overs cricket coming up, with an ICC World T20 in Bangladesh in March and just over a year away from the ICC Cricket World Cup in New Zealand and Australia.

''These two series against Australia allow valuable opportunities for players to push for places in both squads - and given the rivalry between the sides both series will no doubt be keenly contested.''

 Jordan and James Harris and shared six wickets for the England Performance Programme in Western Australia 2nd XI's 319 for eight declared in Perth.
The hosts chose to bat in sweltering conditions at the James Oval, and kept the tourists out in the sun for 86 overs.
Tim Armstrong top-scored with 75, but Harris (three for 58) and Jordan (three for 83) - the latter named on Tuesday in England's one-day international squad to face Australia next month - stuck to their tasks.
In eight overs of batting before stumps on day one of three, EPP lost Varun Chopra lbw to Matt Dixon before closing on 34 for one.
