BRISTOL city councillors will have the chance to scrap the green spaces plan tomorrow.

A motion is due to be discussed at the full council meeting at Council House, College Green, at 2pm.

But politics is threatening to get in the way, with all three main parties putting forward motions of their own that could split any vote.

As an alternative to the Tory motion to abandon the plan, Labour says residents should be given the choice over which sites are sold off and so-called Section 106 money raised from developers should fund improvements to parks.

The Liberal Democrat option is to "note the overwhelming success of the recent consultation and welcome all the feedback it has attracted".

As the controlling group, the Lib Dems have 38 councillors, Labour has 17, the Tories have 14 and the Greens have one. So if they vote along party lines, the Lib Dems will win and the green spaces plan will continue.

If all the opposition groups were to band together they still wouldn't have enough votes to scrap it unless at least four Lib Dems vote against their own administration.

There are 17 Lib Dem councillors who represent wards where controversial land sales are proposed. They are:

● Peter Levy and Cheryl Ann represent Horfield, where the Friends of Horfield Common have objected to the loss of any green space, and hundreds of people have objected to the loss of Wellington Field.

● Jacqueline Bowles is one of the councillors for Southmead, where people have objected to all four sites threatened with sale – Elderberry Walk, Embleton Road play area, Font Hill Park and Trymside open space.

● Sean Emmett and Guy Poultney represent Lockleaze, where groups like Lockleaze Voice oppose any development on Lockleaze open space.

● Peter Main and Jackie Norman represent Brislington West, where more than 1,000 people have signed a petition against the loss of green space.

● Sylvia Doubell and Jos Clark represent Hengrove, where the council wants to sell Briery Leaze despite knowing local residents want it registered as a town green.

● Tim Leaman and Simon Rayner are in Kingsweston, which includes the Sea Mills playing pitches used by more than 300 young footballers.

● Tim Kent is one of the councillors for Whitchurch Park, which includes Pigeon House Steam. Residents have collected a petition with more than 120 signatures against selling part of this land.

● Muriel Cole and Steve Comer are in Eastville, which includes the Snowden Road open spaces local residents have been fighting to keep.

● Patrick Hassell is one of the councillors for Hillfields, which includes the Lodge Hill open space more than 1,000 people have signed a petition against losing.

● Fi Hance and Sylvia Townsend represent Redland, which includes the bowling club the council said didn't exist. Members of the 100-year-old club were furious at the council's plans to redevelop their beloved green.

Thousands of people have signed petitions against the loss of any green space in any part of the city.

Of the 14 areas the council has divided the green spaces plan into, four of them have no green spaces up for sale.

The majority of the decision-making cabinet are within these less contentious areas, including council leader Barbara Janke, Simon Cook, Anthony Negus, Clare Campion-Smith, Bev Knott and Mark Wright.

Only Gary Hopkins (Knowle) and Jon Rogers (Ashley) represent areas where land could be sold, but the proposed sales are not believed to be strongly opposed by residents.

Of the 18 councillors in the "no sale zones", there are ten Lib Dems, representing Cabot, Clifton, Clifton East, Henleaze and Bishopston wards; four Tories in Westbury-on-Trym and Stoke Bishop; three Labour councillors and one Green in Southville and Bedminster.

Tory chief whip Councillor John Goulandris said: "We hope to win the vote by the force of our arguments and the support of the public. We know just how important green spaces are to the quality of peoples' lives. That's why we are moving our motion – core belief not pragmatic political gain."

Labour leader Helen Holland said: "Labour councillors say that local people should decide which green spaces they really value – and choose how the money, which already exists to improve parks through Section 106 funds, can easily cover the costs of these planned works.

"This has the benefit of getting the money out of the council's coffers, to spend on the issues that it was designed for, and also giving much more real power to existing neighbourhood partnerships."

Mrs Janke said: "There has been a record response to the consultation, which we welcome. This has been a highly effective exercise, which has drawn attention to the sensitivity surrounding some of the sites included as possible options.

"We can assure all of those members of the public who took part that their views and the information they shared with us will be taken fully into account and, where appropriate, adjustments will be made in the proposals to reflect this feedback."

If the scheme continues then a list of the sites to be sold off is due to be revealed in December, pending a final decision by the cabinet.

Mr Hopkins has said sites not sold will be protected from development for 20 years.
