The Conservatives are outstripping Labour in fundraising by more than a quarter ahead of the next General Election.
David Cameron's party received over £4 million in donations in the first quarter of this year, compared to the £2.8 million raised by Labour.
Despite Labour's inferior flow of funds, their donations are slightly up on the previous three months, while the Opposition's total was about one million pounds down, according to Electoral Commission records.
Donations to all parties in the period were up at £9.1 million in lieu of the recession, but the figures precede the tumult over MPs' expenses which many fear will dissuade benefactors from giving more.
The value of loans still to be paid off by all parties exceeds £20 million.
The Commission also reported that the British National Party had returned five donations from non-permissible sources and that Labour was one of several parties facing investigation for failing to report donations on time.
