TOKYO, Jan 31 (Reuters) - Fujitsu will not abandon or significantly shrink its European businesses, chief financial officer (CFO) Takeshi Isobe said at the company's earnings briefing on Wednesday.

But Fujitsu must work to recover credibility after a scandal in which hundreds of Post Office workers in Britain were wrongly convicted of theft, fraud and false accounting because of glitches in software developed by the company, Isobe said.

The group has said it will refrain from bidding for new UK government projects in the aftermath of the scandal, but would continue to work on existing projects.

Isobe said Fujitsu did not expect an immediate financial impact in its fourth quarter and was currently investigating the potential impact on the next financial year, which begins in April. (Reporting by Anton Bridge Editing by Mark Potter)
