stalemate in pension strike talks talks aimed at averting national strikes over pension reforms have ended without agreement after 90 minutes.  five public sector unions met deputy prime minister john prescott at the labour spring conference in gateshead. they want the government to withdraw regulations - due to be introduced in weeks - which would raise the pension age for council workers from 60 to 65. up to 1.4 million workers could take part in strikes earmarked for 23 march. discussions will resume next week.  a spokesman for unison  britain s biggest union  said after saturday s meeting:  at least we are still talking.  all sides are anxious to avoid a major confrontation in the run up to the general election  said bbc labour affairs correspondent stephen cape. in four days  unison will start balloting 800 000 local government workers on strikes. other public sector unions have pledged to follow. the five unions which met mr prescott want the government to withdraw these regulations. this would allow months of tough negotiations to follow  said our correspondent. but a spokesman for mr prescott warned that the changes to the local government pension scheme would have to go ahead in april.  privately ministers believe this will be the  less painful  option  our correspondent added. the public and commercial services union (pcs) will co-ordinate any industrial action with up to six other public sector unions. pcs leader mark serwotka warned last week that there could be further walkouts unless there was a government rethink.  for a government that lectures everyone on choice - choice on public service  choice on this and choice on that - isn t it ironic that they re saying to public sector workers there is no choice   he said.  if you want the pension you were promised when you started you must work for an extra five years - that is working until people drop.  in the 20th century  it s completely unacceptable.   unison s 800 000 workers  the transport and general workers  union s 70 000 and amicus  20 000 are among those being balloted about a 23 march walkout. mr prescott held a private meeting with senior union figures last week. it is understood no deal was offered in that meeting but there was room for further negotiations.
