G20 countries should ensure they have plans to withdraw the huge stimuli put into their economies but are clear they must remain in place for now, a UK government source told Reuters on Wednesday.

It is vital that countries have an exit strategy but we are very clear that interventions need to remain in place for as long as needed, the source said ahead of a meeting of Group of 20 finance ministers and central bankers in London next week.

The meeting will emphasize the significant progress that has been made but make it clear that more has to be done.

The source said that there was also expected to be some discussion on bankers' pay.

It can't be return to the old ways of high risk behavior by financial institutions, the source said.
