Pet project - Cut council tax precept by at least 10% over a term.

Ken Livingstone, the Labour mayoral candidate, has produced a 100 page manifesto for the next four years. His "Better Off pledge" to Londoners covers six key promises.

Transport The Fare Deal pledge offers "across the board" fares cut averaging 7% in October, frozen next year, with a promise of no above-inflation rises for the remainder of the mayoral term; pledges to run Transport for London public information campaigns courtesy on public transport, and pilot a "cyclists only" green traffic light phase to give them a few seconds' start to pull away to improve safety.

Crime and policing: reverse police cuts Livingstone claims took place under Johnson's watch (numbers have fallen overall by 1.17% since 2009, according to Met figures, to 32,159) and put them back up to 2010 levels achieved under Johnson (33,260); Safer Neighbourhood teams to be beefed up to nine officers (up from six), each with their own sergeant; assigned police officer to every school that wants one.

Housing set up a London lettings agency to reduce rents by cutting out the profits of "rip-off letting agents"; free insulation for 400,000 households to cut bills by an average of £150 a year; create a "landbank" which would release GLA land on long term equity share basis to housing associations and other developers; build 35,000 new homes a year, and restore 50% target for affordable homes.

Economy A London energy co-op run from city hall to provide cheaper energy bills, saving up to £120 a year; restore the educational maintenance allowance of £30 a week for 16-19 year olds; extend "genuine apprenticeships" for all 16-18 year olds who want them and a pre-pilot apprenticeship course to help support 1,000 young people with basic skills. Lobby for national insurance tax breaks to encourage small businesses to hire extra staff, provide a London-wide business support service.

Pet project A full grant for the upfront costs of childcare up to £700 for approximately 1,200 families, with a view to expanding it to take in more low income families later.

Brian Paddick, a former senior Met officer and now Liberal Democrat mayoral candidate, has pledged:

Transport Targeted fare cuts, including an one hour bus ticket, a part timers' travel card and early bird discount for commuters using network before 7.30am.

Crime and policing New policing ombudsman for London to enforce "tough and clear" standards of conduct over policing, including tackling abuses of stop and search and racist attitudes; work with voluntary groups to better support rape victims and bring in police performance measures based on assessment by rape survivors who have contact with the police; involve local people in neighbourhood policing plans; restore number of police to peak of 33,500 and put more police on streets in areas most at risk from gun and knife crime.

Housing bring 50,000 empty homes back into use; set up a London Housing Company to match public land to private investment; 360,000 new homes "of all types", including a big increase in a "well-regulated private sector"; targets for tackling overcrowding.

Economy Set up a small business fund and work with socially responsible banks to get small firms the finance, mentoring and advice they need; set up a London Green investment bank; offer every young jobless Londoner a youth contract to ensure work or learning linked to genuine job opportunity.

Pet project Set up seven day a week youth hubs for young people, funded by the banking sector and a voluntary £1 nightly bed tax paid by those staying in four and five star hotels in the capital.

Jenny Jones the Green party mayoral candidate. She currently sits on the London assembly and is first on the Green party list for the assembly elections, has summarised her Green party mayoral aims in a 15 page manifesto. Pledges include:

Transport New congestion charge zone near Heathrow; increase the congestion charge from £10 to £15 and £40 for "gas guzzlers", and replace it with a London-wide pay-as-you-drive scheme in three years as part of measures to reduce pollution, ease congestion and improve road safety for everyone, including cyclists and pedestrians; aim to make at least a third of tube step-free by 2018.

Crime and policing End use of kettling tactics to contain lawful demonstrations; put CCTV cameras in all police vans; get more police officers on foot or bicycles to provide a more visible presence on streets; commission community and voluntary organisations to investigate how to improve relationship between police and local community, a one-stop shop for domestic violence in every borough; wholesale reform to give Independent Police Complaints Commission "real teeth."

Housing Aim to build at least 15,000 permanently affordable homes, and only provide land and public funding to those who build homes that charge an London affordable rent level; insulate at least one million homes by 2015 and bring them up to an enhanced Decent Homes Standard to help cut fuel poverty and CO² emissions; set up a clearing house to offer all publicly owned derelict land to community land trusts.

Economy Establish a fair pay mark recognising firms that pay at least the London living wage (£8.30) publish their own wage gap and commit to reducing it; create at least 150,000 high quality apprenticeships aimed at the under 25s; ensure "best value" bids factor in wider social, economic and environmental implications, rather than just cheapest price.

Pet project ensure air pollution is monitored in the right places and alert public to bad air episodes.

Siobhan Benita, a former Whitehall civil servant and the only candidate standing on an independent ticket

Transport

Freeze fares until at least April 2014; keep tubes running one hour later on Friday and Saturday nights; support and promote a third runway at Heathrow airport; keep up the momentum of improvements to the tube, progress proposals for Crossrail 2 and 3 projects and explore all options for a river crossing in East London.

Crime and policing Launch a fully independent review of the Met police in a bid to modernise, and increase trust in service; strengthen Safer Neighbourhoods teams and extend operating hours; guarantee continuation of funding for all four rape crisis centres in London for entire term and work with boroughs to expand provision across the capital; set up a thousand-strong Young Londoners Support Team to target areas where gangs are most active and provide on-the-ground advice and practical help to children most vulnerable to criminal activity.

Housing Set up a "fixed-price" housing market by gifting GLA land for property development to deliver at least 20,000 homes at £100,000-£150,000 each year. A lottery would decide who would be allowed to buy the property, whose prices would be increased each year by the mayor; restore the 50% target for "genuinely affordable homes" scrapped by Boris Johnson; bring 40,000 unused and derelict buildings back into use, and work to eradicate homelessness.

Economy Set up an Office for budget responsibility for London to provide an independent analysis of the city hall finances; work with councils and businesses to make sure that apprenticeships are effective in delivering employment and career prospects; remove barriers to those under-represented in apprenticeships by working with businesses, schools and colleges.

Pet Project - Appoint an independent education commissioner for London who would overhaul access to secondary schools and work with teachers and employers to ensure young people have the right skills by the time they leave school.

Lawrence Webb the UKIP mayoral candidate. Many pledges are part of the "lobbying list" UKIP would bring to the government's door for changes it wants to see in the capital

Transport Scrap congestion charge cameras (effectively scrap the congestion charge, which UKIP sees as anti-business); fight the new HS2; introduce 20 minute parking across London; allow taxis to use the Olympic VIP lane; make all new taxis VAT exempt and crack down on illegal minicabs.

Crime and policing Change procedures to make it easier for people to make a citizen's arrest for vagrancy, drunkenness, weapons and low level disorder "to help improve Met clear up rates", and introduce an "offend on Saturday, face court on Monday" zero tolerance approach to gangs, knife crime and antisocial behaviour.

Housing Halve council waiting lists by filling empty properties from a central register and prioritising the needs of long term Londoners; cut VAT on refurbishment of existing buildings.

Economy Prioritise Londoners for jobs and housing over migrants and asylum seekers; cut rates for local businesses, fight EU red tape "strangling" London businesses.

Pet Project Give landlords the power to decide if they want smoking rooms in pubs and clubs.
