THE Greens and Liberal Democrats spend the last day campaigning pushing their key policies in a bid to increase their number of MSPs.

The Greens are hopeful of a major breakthrough with polls suggesting as many as between eight and 12 could be possible.

The LibDems are looking to boost their numbers back up from the five they won in their lowest Holyrood showing in 2011.

Patrick Harvie, co-convener of the Scottish Greens launched the party's final push for votes in visits in both Edinburgh and Glasgow.

He met Edinburgh candidates Alison Johnstone and Andy Wightman at the ‘Green Tardis’ in Leith before heading to Glasgow to campaign with fellow city candidate Zara Kitson.

The pair visited the Fred Paton Day Centre to highlight the Greens' policies on social care, including a Living Wage Plus for care workers and a rise in the unpaid carer's allowance to £93.

Mr Harvie said: "This has been the biggest Green campaign to date and our teams of campaigners throughout Scotland are working hard to win every crucial vote. With Labour in decline and the SNP lacking a constructive challenge, it's never been more important to vote Green.

"Our aim is Green representation for every region of Scotland. Voters across the country are telling us they are considering how best to use their two votes.

“By casting a regional vote for the Scottish Greens, people can be sure of bringing new voices into parliament to champion the bold ideas our country needs."

The Liberal Democrats hope to win back a Glasgow MSP having lost Robert Brown at the last election.

LibDem leader, Willie Rennie, said the party’s plan to raise tax for education was proving popular with the voters.

He said: "This is a historic election where Scots have the chance to choose how the new powers in the hands of Holyrood are used for the next five years.

"Our ambitious and positive penny for education guarantees a transformational half a billion pounds for education to make our nurseries, schools and colleges the best again.

"Voters like what we're saying and the way we're saying it. If they want that investment in education, in mental health services, and for our civil liberties and environment to be protected, vote Liberal Democrat today."
