England's hopes of forcing a series-levelling win in the fourth Ashes Test were again frustrated by rain as bad weather delayed the start of Sunday's final day at Old Trafford.

Heavy overnight rain left the outfield sodden and a planned inspection by the umpires at the scheduled start time of 11:00 am (1000 GMT) was abandoned as fresh showers hit the Manchester ground.

But with hardy spectators still sheltering beneath umbrellas, ground staff began removing the covers at 11:45 am (1045 GMT) as mopping-up operations got underway.

Australia are 214-5 in their second innings, still 61 runs behind England's first-innings 592, after rain meant only 30 overs' play was possible on Saturday's fourth day.

England managed to take just one wicket in that time when part-time off-spinner Joe Root had Marnus Labuschagne caught behind, but not before the Australia No 3 had held up the hosts' victory charge with 111.

Ben Stokes's home team must win at Old Trafford to square the series at 2-2 and force a decider in next week's fifth and final Test at the Oval in London.

But a draw would be enough for Australia, as the holders, to be assured of retaining the Ashes, with Old Trafford notorious for weather delays -- the ground has had 24 complete days rained off in Test cricket, plus an additional two entire Tests abandoned.

England restricted world Test champions Australia to 317 in their first innings of this match before racing to 592 all out, thanks largely to opener Zak Crawley's breathtaking 189 and an unbeaten 99 from Jonny Bairstow.

Fast bowler Mark Wood ripped through Australia's top order on Friday with a superb burst of 3-17, dismissing Usman Khawaja, Steve Smith and Travis Head.

But Australia kept England at bay on Saturday during a stand of 103 between Labuschagne and all-rounder Mitchell Marsh (31 not out).

England are bidding to become just the second side in Ashes history to win a series from 2-0 down.

The Australia team of 1936/37, inspired by batting great Don Bradman, overturned that deficit to win 3-2.

The tourists won a nail-biting first Test at Edgbaston by two wickets before winning the second match at Lord's by 43 runs.

England bounced back to win the third game of the series at Headingley by three wickets.
