The Conservatives raised three times as much as Labour in the last quarter boosted by £10m from the will of supermarket tycoon John Sainsbury, showing they are on course to benefit from No 10’s decision to raise election spending limits.
The Tories brought in £15.8m overall for its election war chest in the three months to September, while Labour drew £3.1m in private donations from individuals and trade unions as well as getting £2.5m in public funds.
