Dear Madam
I am writing with reference to your invitation on diner. It is very kind of you that offered me in centre of day meeting. I would like to accept your invitation but I have already prearranged meeting unfortunately. I am sorry I can not him shift.
I leave to London to meet with Mr Brownk. Could you please come to me on next Friday. Very I ask.
Please find enclosed documents.
I look forward to your early reply.
Best regards
Katarzyna
