Lottery winners donated £500,000 to SNP before election
Christine and Colin Weir have given the party £4.5m since their 2011 jackpot.
EuroMillions winners Christine and Colin Weir handed the SNP £500,000 ahead of June's general election.
The latest figures bring the total which the Ayrshire couple have donated to the party since they claimed their £161m lottery jackpot in 2011 to more than £4.5m.
The SNP also took in a sum of £23,000 from celebrated Glasgow artist Gerard Burns in the last financial quarter.
The figures published by the Electoral Commission show that in the three months from April to June, political parties across the UK received a record £40.1m in donations.
This was £9.4m more than the previous highest quarter on record, which occurred in the run-up to the 2015 general election.
The Conservative Party received more than all the other parties put together, taking in nearly £25m from donors compared to £9.5m for Labour, £4.4m for the Liberal Democrats and £596,000 for the SNP.
In total, parties received more than quadruple the amount they were given during the first three months of 2017.
This reflected the short time parties had to build up their election war chests after Theresa May's surprise decision to call a snap election in April.
