please can some one help me?

Basically you have redyed the leather. If the nail polish will not peel off (carefully) then it will need to be removed with solvents which will also remove finish and pigment which will then need replacing.

This job is best left to a qualified leather technician.

You should not try using nail varnish remover as this will definitely damage the finish on your leather. If it does remove the varnish it will also remove finish and pigment.

Please call a leather specialist to fix this.

Try dabbing the affected area with small amounts of acetone using a paper towel. First test it on an inconspicuous area. Keep dabbing until no more nail polish is coming up on your paper towel. If the acetone damages the leather you can try using rubbing alcohol. Use the same method of dabbing. If neither works you could try contacting a leather professional. They have access to more chemicals and should be able to remove the stain.
