The Conservatives have raised £5.7m in the first week of the official election campaign, according to the Electoral Commission.
The Tories received 87% of registered donations in that period, figures show, while Labour raised a total of £218,500.
The Lib Dems received £275,000, whilst the Brexit Party raised £250,000.
But the figures do not represent all donations, as only those above £7,500 have to be reported.
The biggest gift to the Tories was £1.5m from theatre producer and regular donor John Gore.
Meanwhile the biggest donation to Labour was £62,000 from the Unite union, led by Jeremy Corbyn ally Len McCluskey.
