The Lib Dems are totally untrustworthy. Say one thing and do another eg Student fees/voted for Tory Government cuts. Sponsored the Gagging Act that made it a criminal offence for Charities to make any comment that could be deemed 'political'. Locally ( no shame), look around for what other people are campaigning for and pretend they did it, say one thing in Tory areas, the opposite in Labour ones, voted for our local council to have a 60% cut in Government funding when Tory ones got a rise then complained it doesn't fund things.
Conservatives - not interested in the majority population at all - just protect the rich, their schools ( tax relief), their off shore tax havens, would sell anything to anyone to make themselves money - support vicious Governments ( Saudi Arabia ), privatisation of NHS / prisons / railways/ most public services and make a mess of them. Attacked Legal Aid,/funding for anything public - education ( large class sizes ), poor Teacher/Nurses' pay, starve BBC of money then complain it can't make good programmes, sell off anything and everything to foreigners/ their friends, leaving us with no industry etc. Make people who lost jobs /are ill wait (at least) 5 weeks for pitifully poor Universal Credit! Whole ethos is against public provision, think everyone should look after themselves!!! Tough if you can't. It's your own fault.The nasty party.
Labour - at least believe in the Welfare State ie Old Age Pensions, will protect NHS ( they founded it), will fund our public Education, will listen to concerns of the mass of people, will listen to Trade Unions, restore Legal Aid, look after those in Care homes, fund home care , fund local councils.
No contest - vote Labour for civilisation.
