Senior Napthine government minister Matthew Guy has denied he held talks with balance-of-power MP Geoff Shaw over changes to Victorians abortion laws.

Labor has seized on a report in The Austra-lian on Thursday morning which details letters between Premier Denis Napthine and Mr Shaw in the months after the former Liberal MP quit the party.

The report says Dr Napthine's letter reveals that the Premier or his staff contacted parliament's chief counsel about getting a private members bill for Mr Shaw drafted.

No bill has been tabled in parliament yet regarding changes to Victoria's abortion laws.
