TOKYO, Oct 27 (Reuters) - Japan's Nikkei share average

climbed past the 50,000 level for the first time on Monday,

continuing a run of successive records on expectations of

sizeable spending from the nation's new prime minister.

Crossing the key psychological threshold is the latest

milestone for the blue-chip share gauge that has been red hot

since fiscal dove Sanae Takaichi began her ascent to power.

The Nikkei 225 Index jumped 1.5% to 50,059.59 in

early trading.
