Two-thirds of MPs consider making charities more transparent to be a priority, research by the consultancy nfpSynergy shows.
A survey of 125 member of parliament carried out in the summer found that 66 per cent chose "making charities more transparent" as a priority from a list of suggested answers.
About a third of those that selected making charities more transparent said it was their top priority for the sector.
MPs could select more than one answer from the list, which also included finding more funding sources, which came out as the second most popular answer from those that chose it as their top priority, and preventing chief executive pay of more than £200,000 a year, which was third. Only one response could be chosen as their top priority.
Slightly more than a third of respondents said they wanted to prevent charities that received government funding from lobbying, and a similar proportion said they wanted to prevent private schools fom being charities.
The top priority for the Conservative MPs polled was making charities more transparent, while repeal of the lobbying act was the most popular answer selected by Labour MPs.
Joe Saxton, co-founder of nfpSynergy, said the research showed that Conservative MPs would keep up the pressure on charity lobbying, and that the lobbying act was not going to repealed any time soon.
