It is not the first time since parties agreed a snap general election should take place that Johnson has faced claims his government misused public resources.
Facebook ads trumpeting government investment aimed at marginal, mainly Brexit-voting towns were published the day Labour backed the snap poll, attracting claims ministers were using government money to campaign.
It was also reported that Johnson’s chancellor, Sajid Javid, had ordered a Treasury analysis of Labour’s policies, but the move was halted after complaints from Jeremy Corbyn’s team.
Johnson and no-deal minister Michael Gove were also accused of breaching the ministerial code after using public funds for a no-deal Brexit ad campaign claimed to be “nakedly partisan”.
Billboards, mugs and newspaper adverts warning people to ‘Get Ready For Brexit’ on October 31 were green-lighted by the PM and cabinet minister Gove and paid for with £100m of public cash.
But a cross-party group of MPs, led by Lib Dem leader Jo Swinson, claimed the campaign was based something which could not be government policy backbenchers made a Halloween no-deal Brexit illegal.
