The Conservatives spent more than £16 million on the last general election campaign, a watchdog has said.
The Electoral Commission stated that the party spent £16,486,871 across the country in order to gain its 80-seat Commons majority in December 2019.
The biggest chunk of the money, £5,818,998 went on “unsolicited material to electors”, the commission said.
Marketing and canvassing cost £4,471,937, and advertising came in at £3,011,665.
Rallies and other such events saw £529,650 spent on them.
Figures for the Labour Party have yet to be published as its financial submissions to the commission were late due to the coronavirus outbreak.
The report shows that the cost of the SNP campaign was £1,004,952.
Plaid Cymru spent £183,914 in the December election, and the Independent Group for Change paid out £29,556.
The cost of the Ukip general election push was £8,761.
The figures for other parties will be released in batches, the commission said.
