A memorial service will be held later for former Labour MP Tam Dalyell.
The veteran politician and father of the West Lothian Question died last month aged 84 following a short illness.
The ceremony is being held at St Michael's Parish Church in Linlithgow.
Mr Dalyell's body was donated to science in line with his wishes, followed by a private interment.
The Old Etonian baronet spent 43 years as an MP after being elected to represent West Lothian in 1962.
He became MP for Linlithgow 21 years later and was named Father of the House, the longest continuously serving MP, in 2001.
A fervent opponent of Scottish devolution, Mr Dalyell's famous constitutional challenge, "Why should Scottish MPs at Westminster be able to vote on English matters when English MPs would be unable to vote on Scottish issues," became known as the ''West Lothian question''.
Tributes were paid to him from across the political spectrum after his death was announced on January 26.
Labour leader Jeremy Corbyn called him a ''titan of parliamentary scrutiny'', while Scottish First Minister Nicola Sturgeon said he was a ''real giant'' of Scottish politics.
A further memorial service is planned for London.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
