Deductions & credits

Thank you Kris,  it is confusing because I had seen this, however as I live in UK, then the property is not 'foreign' to me, and whereas tax on foreign income can be credited/deducted then it seem logical that so should tax paid on one's primary residence be credited/deducted.  Thank you for clearing this up though!  I have another question that maybe you can answer.  I paid an amount  into my spouses government workplace pension (not my own).  Is this deductible?  Thanks
