Has lesions that if irradiated would result in unacceptable radiation induced toxicity to normal tissue, in particular to the CNS and bowel~2. Requires palliative radiotherapy for symptom control~3. Is currently participating in or has participated in a study of an investigational agent or device within 4 weeks of the first dose of trial treatment~4. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment~5. Has had a monoclonal antibody within 4 weeks prior to the first dose of trial treatment or who has not recovered (i.e. ≤Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier~6. Has had chemotherapy, targeted small molecule therapy, or radiation therapy within 4 weeks prior to the first dose of trial treatment or who has not recovered (i.e., ≤Grade 1 or at baseline) from adverse events due to a previously administered agent~   * Note: patients with an AE ≤Grade 2 neuropathy are an exception to this criterion and may qualify for the study~  * Note: if patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy~7. Has history of severe colitis related to previous immunotherapy treatment~8. Has a known additional malignancy that is progressing or requires active treatment Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy~9. Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis~10. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents.~11. Has evidence of interstitial lung disease or active, non-infectious pneumonitis.~12. Has an active infection requiring systemic therapy~13. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the patient's participation for the full duration of the trial, or is not in the best interest of the patient to participate, in the opinion of the treating investigator~14. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial~15. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment~16. Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137~17. Has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies)~18. Has known active hepatitis B (e.g., HBsAg reactive) or hepatitis C (e.g., HCV RNA \[qualitative\] is detected)~19. Has received a live vaccine within 30 days prior to the first dose of trial treatment

Study Arms:
- Pembrolizumab Alone (Type: EXPERIMENTAL): If the patient is randomised to the Pembrolizumab Arm Only then they will receive 200mg of pembrolizumab every 3 weeks.
- Pembrolizumab plus Radiotherapy (Type: EXPERIMENTAL): If The patient is randomised to this arm they will receive 200mg of pembrolizumab every 3 weeks in combination with a radiotherapy dosage of 24Gy in 3 fractions to be given over 3 consecutive days (only).
