Scottish Labour and the SNP have the most accessible election manifestos for disabled people, the One in Five campaign have said.

The campaign produced an 'accessible manifesto report card' judging the main parties on the availability of their manifestos in formats including audio, Braille and British Sign Language (BSL) video.

The One in Five campaign, launched only 14 months ago, seeks to increase the participation of disabled people in Scottish political life.

It is a grassroots, cross-party organisation which brings together activists from the SNP, Scottish Labour, the Scottish Conservatives, the Scottish Liberal Democrats and the Scottish Greens.

The 'report card' rated the SNP and Scottish Labour most favourably, giving their manifestos full marks for accessibility.

The Scottish Greens received 5 out of 7, while left-wing alliance Rise were given 4 out of 7.

The Scottish Conservatives and Liberal Democrats each received 3 marks out of 7.

UKIP Scotland received zero marks, although the One in Five campaign noted they had not signed the One in Five 'charter' as the other parties had.

A One in Five spokesperson said: "We are delighted to see an array of accessible manifestos from across the political spectrum. This is the first Scottish Parliament election since the main political parties signed our charter committing to make politics more accessible to disabled people.

"In recent weeks, the parties have shown a willingness to engage with us, seeking advice in order to maximise their own support."

The spokesperson added: "Whilst cost and underestimating the time it takes to produce accessible manifestos were the most common obstacles, we now have a minimum standard for each party for future elections."

UKIP Scotland responded that most voters don't read manifestos anyway.

A party spokesman said: "UKIP has a very positive attitude towards people with disabilities... However, it is widely recognised that party election manifestos are amongst the most unread documents in existence.

"Parties feel duty-bound to produce them, but never really expect many voters to pick them up and read them.

"Most voters rely on the media coverage, leaflets through the door and the beloved canvassers that are on their doorstep in the middle of Eastenders, for information on each party."

He added: "As a small party, we don't have the same resources and time as others to make the manifesto as accessible as we would like, especially considering it is not a major part of any party's communication strategy."

The SNP welcomed the One in Five campaign's "endorsement".

A spokesperson for the SNP said: "We welcome this strong endorsement of the SNP's accessible manifesto.

"We firmly believe that increasing the participation of disabled people in politics is vital if we are to build the fairer and more inclusive society we all want to see.

"We fully support the One in Five campaign and as well as publishing our manifesto in a variety of accessible formats, we have committed to establishing a £200,000 elected office fund to support disabled people seeking to stand for election in the 2017 local elections."

Scottish Labour said they were pleased to have received "full marks".

A spokesperson said: "We are delighted to receive top marks from One in Five, a vital campaign doing important work.

"The next parliament must make politics more accessible for disabled people."

The Greens said they were committed to ensuring equal opportunities for disabled people.

A party spokesperson said: "The Scottish Greens are pleased to see that the accessible versions of our manifesto ticked nearly all the boxes for the One in Five campaign, coming ahead of other better-resourced parties like the Conservatives or Lib Dems.

"Scottish Greens are hugely committed to ensure equal opportunities for disabled people. We have supported the One in Five campaign and our Disabled Greens network earlier this week launched our mini manifesto for disabled people."

Rise, the new left-wing grouping competing in its first election, acknowledged it still had work to do.

The alliance's national organiser Jonathan Shafi said: "We're pleased that, in our inaugural election campaign, we've been given a solid 4/7 rating by the One in Five initiative.

"However, we acknowledge that we have more work to do. In future elections we hope to up that grade to 7/7.

"People with disabilities in Scotland deserve to have full access to all election and campaign material. We commend One in Five for all the progress they've made in just 14 months."

The Scottish Conservatives also commended the work done by the campaign.

A Tory spokesman said: "The One in Five campaign has been positive for all political parties and like the others we will continue to work to reduce barriers in the way of disabled peoples participation in politics."

The Lib Dems said they had worked hard to make their manifesto accessible.

A party spokesperson said: "We've worked to make our manifesto and policies as accessible as possible to everyone regardless of their background.

"At our heart Scottish Liberal Democrats want to empower every single person living in Scotland so they can engage with politics and have their say on what kind of government they want to see over the next five years."
